mfd: Correct ro and cd implemantion on DM355
This patch corrects the support for MMCSD card detection
and read only feature for SoC DM355.
EVMDM355_ECP_VA4.pdf, from Spectrum digital, suggests that
Bit 2 and 4 should be checked for card detection. However
on the EVM, bits 1 and 3 gives this status, for MMC/SD
instance 0 and 1 respectively. The pdf also suggests that
Bit 1 and 3 should be checked for write protection. However
on the EVM bits 2 and 4 gives this status.
