tegra2: Plumb in SPI/UART switch code
On Seaboard the UART and SPI interfere with each other. This causes the UART
to receive spurious zero bytes after SPI transactions and also means that
SPI can corrupt a few output characters when it starts up if they are still
in the UART buffer.
This updates the board to use the SPI/UART switch to avoid the problem.
For now this feature is turned off since it needs changes to the NS16550
UART to operate.
