mmc: revert deferred resume
Revert MMC_BLOCK_DEFERRED_RESUME feature from SD driver. The feature
was not implemented thread-safe. Fixing it would require a lot
of locking logic at limited value.
Deferred resume has no effect on eMMC, because eMMC will be used right
after resume. For SD card it only saves power between resume and first
SD card access, which is a limited usecase. It does not save power
on normal SD card idle.
