The A83T clock control unit is a hybrid of some new style clock designs
from the A80, and old style layout from the other Allwinner SoCs.
The mmc2 module clock supports a new timing mode. This mode outputs the
clock at half the set rate, and moves the output and sample delays into
the mmc controller. The mmc controller must also be set to use the new
timing mode. In this patch we force the mmc2 module clock to the new
mode, and drop the output and sample phase clocks for it.
