clk: sunxi: Add Allwinner V3S CLK driver

Add initial clock driver for Allwinner V3S.

- Implement USB bus and USB clocks via ccu_clk_gate table
  for V3S, so it can accessed in common clk enable and disable
  functions from clk_sunxi.c
- Implement USB bus and USB resets via ccu_reset table
  for V3S, so it can accessed in common reset deassert
  and assert functions from reset-sunxi.c
