ffdbeee9f6 sdmmc: Add erase command-38. Support erase/trim/discard/sanitize
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.

78fab8a0f9 sdmmc: implement partial DDR support
Works for 3.3V eMMC in 4 line mode.
Not implemented:
- DDR mode for SD cards (UHS-I) also need voltage to be switched to 1.8V.
- 8-line DDR mode for eMMC to be implemented later.
