The A64 MMC clocks don't seem to be fully compatible to A10. The output
and sample phase control has been moved to the MMC module itself.
The dividers are the same, but the additional special "outputs" are gone.

Parents are PLL6(2x) and PLL8(2x) according to manual.

Consequently, the MMC driver now has to control the output/sample phase
with registers 0x140-0x148 instead of

> + <&mmc0_clk 2>;
And there seems to be some new clock divider somewhere which I haven't
found in the manual yet. The clock measured at the CLK pin is always
half the expected rate (even with 24MHz as MMC clock parent, so no
PLL6*2 problem).
