mmc: atmel: Properly fix clock configuration
Timing issue occurs on eMMC not only when modifying the frequency but
also for all the switch command(CMD6). According to the MMC spec waiting
8 clocks after a switch command would be the thing to do.
This patch allows fixing CPU hang observed when trying to changing the
bus width on a eMMC on SAMA5D4.
