9e3866b548 mmc: at91_mci: cleanup: use MCI_ERRORS
A small MMC driver cleanup.

Use the defined AT91_MCI_ERRORS in at91_mci_completed_command() instead
of specifying all the error bits individually.

This kind of transfer is not supported, so don't advertise it and make it
fail early.

be0192aae1 mmc: remove confusing flag
The MMC_DATA_MULTI flag never had a proper definition of what it
means, so remove it and let the drivers check the block count in
the request.

e0cda54e44 bug in AT91 MCI suspend routines
This patch fixes a bug in AT91 mmc host driver, that enables the wakeup
from suspend on card detection pin even if the card detect pin is not
available (==0). If not card detection pin is defined, IRQ0 == FIQ gets
enabled and if some activity is present on that pin, the system gets a
FIQ request, that causes a crash.

ed99c541e0 mmc: at91_mci: fix hanging and rework to match flowcharts
Fixes hanging using multi block operations (seen during CMD25).
Follows closely the datasheet flowcharts.

This piece of code handles better big file writing. I had to take care
of the notbusy signal during write (at91_mci_handle_cmdrdy function) and
to rearrange the AT91_MCI_ENDRX and AT91_MCI_RXBUFF flag usage.
