Some Allwinner clock devices have parent clocks and reset gates itself,
which need to be activated for them to work.
Add some code to just assert all resets and enable all clocks given.
This should enable the A80 MMC config clock, which requires both to be
activated. The full CCU devices typically don't require resets, and have
just fixed clocks as their parents. Since we treat both as optional and
enabling fixed clocks is a NOP, this works for all cases, without the need
to differentiate between those clock types.

The A80 handles resets and clock gates for the MMC devices differently,
outside of the CCU IP block. Consequently we have a separate clock
device with a separate binding for that.
Implement that with the respective clock gates and resets to allow the
A80 taking part in the DM_MMC game.

Add the MMC clock gates and reset bits for all the Allwinner SoCs.
This allows them to be used by the MMC driver.
We don't advertise the mod clock yet, as this is still handled by the
MMC driver.

Since CLK and RESET share common DT compatible, it is CLK driver
job is to bind the reset driver. So add CLK bind call on respective

deassert operations held based on ccu reset table defined from
CLK driver.
Select DM_RESET via CLK_SUNXI, this make hidden section of RESET
