Ian Chen 3b75588b26 mmc: card: Skip secure erase on MoviNAND; causes unrecoverable corruption. 
commit 3550ccdb9d upstream.

For several MoviNAND eMMC parts, there are known issues with secure
erase and secure trim.  For these specific MoviNAND devices, we skip
these operations.

Specifically, there is a bug in the eMMC firmware that causes
unrecoverable corruption when the MMC is erased with MMC_CAP_ERASE
enabled.
