[0/2] clk: keystone: syscon-clk: Enable audio reference clock

Message

TI's AM62 SoC can optionally provide two audio reference clocks
(AUDIO_REFCLKx) to external peripherals. By default the reference clock
is looped-back inside the SoC to a mux that goes to McASP AHCLK, but can
optionally be enabled as an output to peripherals outside the SoC by
setting a bit through the syscon (CTRL_MMR) registers.

This patch series extends the existing syscon-clk driver to support
the audio reference clock, and also adds new device tree bindings
documentation.
