clk: sunxi: Add apb0 gates for H3sunxi-clocks-for-4.6
This patch adds support for APB0 in H3. It seems to be compatible with earlier SOCs. apb0 gates controls R_ block peripherals (R_PIO, R_IR, etc). Since this gates behave just like any Allwinner clock gate, add a generic compatible that can be reused if we don't have any clock to protect.
