e0c7ce7e52 sunxi: clk: A80: add MMC clock support
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.

bb3e5aa289 sunxi: clk: add MMC gates/resets
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.

6901aab8e3 clk: sunxi: Add Allwinner A80 CLK driver
Add initial clock driver for Allwinner A80.

- Implement UART bus clocks via ccu_clk_gate table for
  A80, so it can accessed in common clk enable and disable
  functions from clk_sunxi.c
- Implement UART bus resets via ccu_reset table for A80,
  so it can accessed in common reset deassert and assert
  functions from reset-sunxi.c
