mmc: card: Skip secure erase on MoviNAND; causes unrecoverable corruption.
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.
