arm64: dts: qcom: qrb5165-rb5: add compressed playback support

Audio DSP supports compressed playback on this SoC. It is required
to add compressed DAI and separate MultimeMedia DAI link to enable this.

Fcplay or cplay tools from tinycompress can playback, say, mp3 files:
fcplay -c 0 -d 3 test.mp3
