Add a driver so the clocks/resets for these peripherals (especially I2C,
RSB, and UART) can be enabled using the normal uclass methods.

The 32kHz clock ("LOSC") on sunxi SoCs is provided by the RTC. It is
used, among other things, by the XHCI controller in the H6. To be able
to call clk_get_bulk() on the XHCI controller, some device needs to
provide all referenced clocks.
Since LOSC is a fixed-rate always-on clock, implementation is trivial.

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
