mmc-utils: Enable/Disable write protect
In secure write protected mode, the updatability of USER_WP[171],
BOOT_WP[173], TMP_WRITE_PROTECT[12] and PERM_WRITE_PROTECT[13] are
controlled by SECURE_WP_MASK bit in the SECURE _WP_MODE_CONFIG of the
Authenticated Device Configuration Area.
Setting it, enables updating WP related EXT_CSD and CSD fields, and
clearing it vice versa.
Access to the Authenticated Device Configuration Area is regulated via
Authenticated Device Configuration Write Request.
