[ Upstream commit 2f3877d609e7951ef96d24979eb9d163f1f004f8 ]
The cpll clk gate bits had an ordering issue. This led to the loss of
the boot sdmmc controller when the gmac was shut down with:
`ip link set eth0 down`
as the cpll_100m was shut off instead of the cpll_62p5.
cpll_62p5, cpll_50m, cpll_25m were all off by one with cpll_100m
misplaced.
