mmc: card: Skip secure erase on MoviNAND; causes unrecoverable corruption. commit 3550ccdb9d8d350e526b809bf3dd92b550a74fe1 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.
