sdmmc: better calculation of erase timeout
Previous version of the code used a fixed constant (500 ms) for the
erase timeout and added 1 ms for each sector erased.
This commit improves timeouts calculation:
- For SD cards, check if erase timeout information is present in the
  SSR register. If yes, use it for erase timeout calculation.
  Otherwise assume 250ms per erase block, same as Linux does.
- For eMMC assume 250ms per erase block (but no less than 1 second).
  This has to be improved later to use the erase timeout info in the
  extended CSD register.

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.
