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.

fb22c1f182 fatfs: Implementation of disk_status nad disk_initialize for SD/MMC card
FATFS provides a disk status and disk initialize callback which were not
implemented. Implementation has very low impact on SD/MMC speed and
fixes issues, when trying to open file when SD card was removed from
slot and not deinited.

If disk_status returns STA_NOINIT, it will always continue with
disk_initialize. If that returns 0, it will continue like everything is
working normally. So there has to be the same check as in disk_status.
Return of disk_initialize is always checked like this for STA_NOINIT or
STA_PROTECT so if command fails, we return the STA_NOINIT.

stat = disk_initialize(pdrv);
if (stat & STA_NOINIT) return FR_NOT_READY;
if (stat & STA_PROTECT) return FR_WRITE_PROTECTED;

Closes IDF-4125
