powerpc/p2041rdb: set sysclk according to status of physical switch SW1
P2041RDB supports 3 sysclk frequencies, it's selected by SW1[6~8], software need to read the SW1 status to decide what the sysclk needs. SW1[8~6] : frequency 0 0 1 : 83.3MHz 0 1 0 : 100MHz others: 66.667MHz Signed-off-by: Shaohui Xie <Shaohui.Xie@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
