[09/42] clk: at91: clk-i2s-mux: add support for parent_hw

Commit Message

Claudiu Beznea July 27, 2023, 5:31 a.m. UTC

Add support for parent_hw in i2s mux clock driver.
With this parent-child relation is described with pointers rather
than strings making registration a bit faster.

All the SoC based drivers that rely on clk-i2s-mux were adapted
to the new API change. The switch itself for SoCs will be done
in subsequent patches.
