clk: sunxi-ng: sun50i: h6: Add 2x fixed post-divider to MMC module clocks
On the H6, the MMC module clocks are fixed in the new timing mode,
i.e. they do not have a bit to select the mode. These clocks have
a 2x divider somewhere between the clock and the MMC module.
To be consistent with other SoCs supporting the new timing mode,
we model the 2x divider as a fixed post-divider on the MMC module
clocks.
This patch adds the post-dividers to the MMC clocks, following the
approach on A64.
