mmc: at91_mci: enable large data blocks
This patch is setting some max_ variables for the IO elevator, so the
elevator will put requests for large data blocks to the driver. This is
critical for
a) speed
and
b) wear leveling of the flash chip controller: Otherwise the controller
will treat the SD card badly with millions of single 4 KByte write
commands. This will lead to a shorter life time for the SD cards.
