[PATCH v4 3/4] clk: rockchip: Add composite clock macro with mux table

[Cunhao Lu via B4 Relay]

From: Elaine Zhang <zhangqing at rock-chips.com>

Some Rockchip composite clocks use mux selector values that do not
match the order of their parent clocks.

Add COMPOSITE_MUXTBL to describe the parent-to-selector mapping along
with the divider and gate. The RK3572 audio clocks use this layout.
