arm64: dts: rockchip: Configure MCLK for analog sound on NanoPi M5

Browse source

commit 3e4a81881c upstream.

NanoPi M5 derives its analog sound signal from SAI2 in M0 pin mode, so the
MCLK pin should be configured accordingly for the sound codec to get its
I2S signal from the SoC. Request the required pin config.

The clock itself should also be CLK_SAI2_MCLKOUT_TO_IO for the sound to
work (otherwise there is only silence out of the audio out jack).
