ARM: 5667/3: U300 SSP/SPI board setup and test
This adds a U300 board configuration for the PL022 SSP/SPI PrimeCell driver recently merged to the 2.6.31-rc series. Further it adds a dummy loopback SPI chip that can be used for testing the SPI functionality on a running system using the loopback mode of PL022.
