spl, mtd, nand, atmel_nand: invert device ready pin logic
device ready pin is signalling that the device is ready on state 1 not on 0. Simmiliar as it is in drivers/mtd/nand/nand_spl_simple.c Signed-off-by: Heiko Schocher <hs@denx.de> Reviewed-by: Andreas Bießmann <andreas.devel@googlemail.com> Reviewed-by: Bo Shen <voice.shen@atmel.com> Acked-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>
