  at91rm9200: fix spi cs support (2012-11-06 04:39:09 +0800)

----------------------------------------------------------------
atmel spi support fix

The current drivers for atmel have a lot of issues but we are lucky
enough if you use it one device + one master instance it will work on
most of the spi device

but this will not work on mmc spi or multi-master instance or multi-device

so now fix all those issues
 - fix the cs support
 - fix setup setup support
 - do not call setup before each transfert
 - add sanity check

now the atmel spi work on rm9200, mmc spi and at24, at45, eeprom
