sdmmc: Add erase command-38. Support erase/trim/discard/sanitize

Browse Source 
options.

Erase command (38) for SD cards allows option for erase/dicard/fule
operation at block level and for MMC cards supports option for
discard/trim at block level. When Sanitize is executed only the
portion of data that was unmapped by a Discard command shall be
removed by the Sanitize command.

Unit test cases added to verify ERASE feature in SD/SDSPI mode.
TRIM/DISCARD/SANITIZE tests for eMMC devices.
