Since the input frequency of the API is a maximum that should not be exceeded in
order for the devices to operate properly, the SPI clock divider should be
rounded up, not truncated.

The SPL doesn't need the CP15 reconfiguration, as that's what the
BootROM does for us already. Moreover, when the CP15 is reconfigured
and the code returns control to BootROM, the USB boot works no more.
Remove the code and allow [1] to work properly as well.

This fixes the SPL build to link with the SPL version of libgcc if

Add support for tegra20 arm7 boot processor. This processor is used
to power on the Cortex A9 and transfer control to it. In tegra this
processor is an ARM7TDMI not an ARM720T, but since we don't use cache
it was easier to just reuse the ARM720T code as the processors are
otherwise identical except for cache and MMU.
