Subject: [PATCH v1 1/2] rm64: dts: ti: k3-j722s-evm: explicitly use PLL1_HSDIV6 audio refclk

The parent of the audio_refclk0/1 is about to change to a sane default
value. Thus, move the (soon to be) non-default value into the board
device tree.

Signed-off-by: Michael Walle <mwalle@...nel.org>

It appears that the eval system just need *any* clock rate for the audio
codec.  Thus, if it's confirmed to be working with the new default
value, this patch might be ignored.
