drivers: mmc: Fix some issues with MMC stack
Some bugs in MMC stack needs to be fixed:
- scr cannot be local as this will cause cache issue when invalidating
after the read DMA transfer is completed
- ACMD41 needs to send voltage information in initialization, otherwise the
command is a query, thus will not initialize the controller
- when checking device state, retry until the retries counter goes to zero
before failing
