Add support for building U-Boot SPL for Renesas R-Car Gen4 R8A779G0 V4H SoC.
The SPL initializes the DBSC5 DRAM controller, RT-VRAM and loads and starts
U-Boot proper on the Cortex-A76 core.
The SoC BootROM can not boot the CA76 core directly, instead the SPL starts
on the CR52 core which immediately brings up the CA76 core, which in turn
starts executing the actual SPL. This is achieved by placing a tiny bit of
precompiled Aarch32 code at the very beginning of the SPL. The code consists
of some 32 instructions, uses APMU to configure CA76 start address to offset
0x80 Bytes from start of the SPL, and uses APMU to start the CA76 core. The
code parts the CR52 core in an endless loop once the CA76 core got started.
The 32 instructions are completely arbitrary number, so is the offset 0x80
Bytes from start of SPL, because 0x80 = 128 decimal and 128 / 4 bytes per
instruction is 32 instructions. The 32 instructions turned out to be enough
to started the CA76 and 0x80 is nicely aligned.
Once the SPL completes hardware initialization, the SPL loads U-Boot proper.
The u-boot.itb proper fitImage contains 64bit build on u-boot-nodtb.bin and
a DT for R8A779G0 V4H White Hawk board and is generated by binman. The
u-boot.itb is loaded from SPI NOR offset 0x80000.
In order to install this setup on an existing R8A779G0 V4H White Hawk board,
build using r8a779g0_whitehawk_defconfig, generate SPI NOR image flash.bin
and write flash.bin to SPI NOR offset 0x0 . Finally, configure board MD pin
switches according to the R8A779G0 V4H White Hawk board documentation for
40 MHz SPI NOR boot using DMA and restart the board.

In case U-Boot runs in EL3, which is the highest privilege level on ARM64,
there can be no firmware running that would restrict access to the bottom
128 MiB of DRAM. In fact, it is likely that U-Boot would have to load that
firmware into those bottom 128 MiB of DRAM and start that firmware.
Make those bottom 128 MiB of DRAM available in case U-Boot runs in EL3 to
allow loading the firmware to that area.

The U-Boot build system can automatically paste -u-boot.dtsi at the
end of matching .dts during build. Stop emulating this behavior and
rename the -u-boot.dts files to -u-boot.dtsi, drop "#include...dts"
from those new u-boot.dtsi files, and update board configuration
accordingly.
The rename, '#include...dts` scrubbing and configuration update has
been done using the following script:
```
$ find . -name r[78]\*-u-boot.dts | sort -u | while read line ; do \
git mv ${line%-u-boot.dts}-u-boot.dts ${line%-u-boot.dts}-u-boot.dtsi ; \
done
$ sed -i '/^#include.*dts"/ d' `find . -name r[78]\*-u-boot.dtsi`
$ sed -i 's@-u-boot@@g' `git grep -li renesas configs`
```
The Salvator-X and ULCB board files have been updated manually.

The Renesas RZ/G2L SMARC Evaluation Board Kit consists of the RZ/G2L
System-on-Module (SOM) based on the R9A07G044L2 SoC, and a common SMARC
carrier board.
The ARM TrustedFirmware code for the Renesas RZ/G2L SoC family passes a
devicetree blob to the bootloader as an argument in the same was
previous R-Car gen3/gen4 SoCs. This blob contains a compatible string
which can be used to identify the particular SoC we are running on and
this is used to select the appropriate device tree to load.
The configuration renesas_rzg2l_smarc_defconfig is added to support
building for this target. In the future this defconfig will be extended
to support other SoCs and evaluation boards from the RZ/G2L family.

The reset_cpu() implementation is basically the same across Gen3
SoCs and identical across Gen4 SoCs. Introduce weak default for
reset_cpu(), so that it does not have to be duplicated in every
board file again.
There is a slight difference for CA53 only systems, like E3 and D3,
which now check MIDR for CPU ID first just like the other systems,
but this is OK since the MIDR always returns CA53 core type and the
correct reset register is written.

As the Renesas Reduced Pin Count Interface may be locked by TF-A, it is
disabled by default[1]. When unlocked, TF-A passes a DT fragment to
enable it, which is applied to the U-Boot DT[2].
Unlike the memory layout, the RPC-IF enablement is not propagated to
subsequent software. Hence e.g. Linux cannot know if the RPC-IF is
locked or not, and will lock-up when trying to access the RPC-IF when
locked.
Fix this by checking if the RPC-IF is enabled in the TF-A DT fragment, and
setting the status of the RPC-IF device node in the target DT, if
present, to "okay". Do this only when a "flash" subnode is found, to
avoid errors in subsequent software when the RPC-IF is not intended to
be used.
Note that this requires the status of the RPC-IF node to be set to
"disabled" in the target DT, just like in the U-Boot DT.

In order to finish moving this symbol to Kconfig for all platforms, we
need to do a few more things. First, for all platforms that define this
to a function, introduce CONFIG_DYNAMIC_SYS_CLK_FREQ, similar to
CONFIG_DYNAMIC_DDR_CLK_FREQ and populate clock_legacy.h. This entails
also switching all users from CONFIG_SYS_CLK_FREQ to get_board_sys_clk()
and updating a few preprocessor tests.
With that done, all platforms that define a value here can be converted
to Kconfig, and a fall-back of zero is sufficiently safe to use (and
what is used today in cases where code may or may not have this
available). Make sure that code which calls this function includes
<clock_legacy.h> to get the prototype.
