It'd be good if someone with some rm9200 board that can boot
from DataFlash tried a version of the atmel_spi config that
leaves CS0 under control of the SPI controller ... updating
the setup code would suffice, ISTR.
Because we know that both atmel_spi and mtd_datflash behave on
other hardware, even for CS0. And ISTR hearing they work OK
on rm9200, for other chipselects...
