gpio38 is used in SOM's kv260 to reset the Ethernet PHY.
At present, HW reset is not working properly as Tri-state
is enabled for MIO38, causing inappropriate PHY register reads.
Disabled Tri-state for MIO38 to make HW reset work.

The following patch migrates the usage of debug and printf functions
to the relevant logging function as per U-Boot DM guidelines.
Additionally some of the debugging statements have been rearanged for
a more meaningfull debug experience.
aarch64-linux-gnu-size reports 229 bytes less when debug is enabled at
file level, while is just 5bytes more when disabled.

The baudrate configured in .config is taken by default by serial. If
change of baudrate is required then the .config needs to changed and
u-boot recompilation is required or the u-boot environment needs to be
updated.
To avoid this, support is added to fetch the baudrate directly from the
device tree file and update.
The serial, prints the log with the configured baudrate in the dtb.
The commit c4df0f6f31 ("arm: mvebu: Espressobin: Set default value for
$fdtfile env variable") is taken as reference for changing the default
environment variable.
The default environment stores the default baudrate value, When default
baudrate and dtb baudrate are not same glitches are seen on the serial.
So, the environment also needs to be updated with the dtb baudrate to
avoid the glitches on the serial.
Also add test to cover this new function.

Older DesignWare Ethernet MAC versions that this driver supports can
only work with 32-bit DMA source/destination addresses. Some platforms
have no physical RAM at the lowest 4GB address space. For these
platforms the driver must translate DMA addresses to/from physical
memory addresses.
Call translation routines so that properly configured platforms can use
the DesignWare Ethernet MAC. For platforms using device-tree this
usually means adding dma-ranges property to the bus the device node is
in.

e1000_eth_ids holds compatible strings for e1000 devices, but it
is meaningless as e1000 is a PCI device and there is no such
compatible string assigned to e1000 by the DT bindings community.

Setting the clock delay from the device tree settings
rx-internal-delay-ps and tx-internal-delay-ps was broken:
- The expected value in the device tree is suppose to be a
delay in picoseconds, but the driver only allowed an array index.
- Driver converted this array index to the actual delay in
picoseconds and tried to apply this in the device register. This
however is not a valid register value. The actual logic here was
reversed, it converted an register representation of the delay to
the device tree delay in picoseconds.
Only when the internal delays were NOT configured in the device tree
and they default value of 7 (=2000ps) was used, a valid value was
loaded in the register.

There is no reason to setup ROM source if read_rom_hwaddr hook doesn't
exist or reading mac address fails. It is ending up with confusion about
mac address source.
It is nicely visible if you put mac address to DT as
local-mac-address = [ff ff ff ff ff ff];
but also save ethaddr to variables
setenv -f ethaddr 02:18:31:7e:3e:01
Before this patch U-Boot prints that source is ROM
Address in ROM is ff:ff:ff:ff:ff:ff
Address in environment is 02:18:31:7e:3e:01
After that source is DT:
Address in DT is ff:ff:ff:ff:ff:ff
Address in environment is 02:18:31:7e:3e:01

Marvell LinkStreet switches support Clause 45 MDIO on the internal bus.
C45 read or writes require the register address to be written first to
the SMI PHY Data register, and then a special C45 Write Address Register
OP is used on the SMI PHY Register before making a C45 Read Data Register
OP and being able to actually read the register.
