[PATCH v2 16/32] clk: at91: clk-i2s-mux: add support for parent_hw

[<Ryan.Wanner@microchip.com>]

From: Claudiu Beznea <claudiu.beznea@tuxon.dev>

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.

going to be coalesced into one SoC specific commit.]
