[ARM] pxa: add pxa3xx NAND device and clock sources
A pxa3xx_set_nand_info() is also introduced to set the PXA3xx NAND driver specific platform_data structure pointer. Signed-off-by: Eric Miao <eric.miao@marvell.com> Cc: Sergey Podstavin <spodstavin@ru.mvista.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
