clk: sunxi: Add Allwinner H3/H5 CLK driver Add initial clock driver for Allwinner H3/H5. - Implement USB bus and USB clocks via ccu_clk_gate table for H3/H5, 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 H3/H5, so it can accessed in common reset deassert and assert functions from reset-sunxi.c Signed-off-by: Jagan Teki <jagan@amarulasolutions.com> Acked-by: Maxime Ripard <maxime.ripard@bootlin.com>
