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.

279ee85305 sdmmc: fix the probe issue that forbid sdspi working in highspeed mode
SD cards don't support CMD7 (select_card) in SPI mode. Highspeed probe
of sdspi will fail in this step and stop working in highspeed mode.
Remove the CMD7 in enable_hs_mode_and_check to fix this issue.

Please note that, on ESP32, you have to use the IOMUX pins to use sdspi
in 40MHz, otherwise the initialization process will report reading issue
and fail.
