[PATCH] SPI: atmel_spi driver

Driver for the Atmel on-chip SPI master controller.

Tested primarily on AVR32/AT32AP7000/ATSTK1000 using mtd_dataflash and the
jffs2 filesystem.  Should also work fine on various AT91 ARM-based chips
like AT91SAM926x and AT91RM9200.

Hardware documentation can be found in the AT32AP7000 data sheet, or its
AT91 siblings, which can be downloaded from
