arm64: dts: ti: k3-j722s-evm: Switch audio codec clock from audio_refclk1 to external clock
In revision PROC170E1 of the J722SXH01EVM [0], the audio codec's
(TLV320AIC3106IRGZT [1]) MCLK was provided by the AUDIO_EXT_REFCLK1
(96MHz). Revisions PROC170E2 and later switched the MCLK's source
to an external LMK6CE012288CDLFT [2] oscillator (12.288MHz). The
PROC170E1 revision of the board is not publicly available.
Fix the audio codec's clock by creating a new fixed clock node with
a frequency of 12.288MHz, and switch the audio codec's clock from
the audio_refclk1 to the new fixed clock. Remove pinmuxing and clock
muxing for the audio_refclk1.
