A previous patch removed the audio PLL configuration from the clk
node, which resulted in an incorrect clock rate when attempting
to playback audio.  Fix this by setting the AUDIO_PLL2 rate inside
the SAI3 node since it's the SAI3 that needs it.

Fixes: 16c984524862 ("arm64: dts: imx8mp: don't initialize audio clocks from CCM node")
