exynos5250: Implement support to boot with USB A-A firmware upload
This patch implements the basic infrastructure required to use the USB
A-A firmware upload feature on Exynos5 processors with Coreboot. It will
require a corresponding host-side script that activates the feature and
uploads the correct image parts in the correct order to harcoded target
addresses, as described in the comments of alternate_cbfs.c.
Also fixes a bug in the Google Snow mainboard where it would not
correctly initialize the pinmux configuration for the SPI flash bus.
During a normal SPI boot the IROM would already do that for you, but
when booting from USB you have to do it yourself.
