arm64: dts: qcom: milos-fairphone-fp6: add WCD9378 codec node and capture dai-link

Browse source 
Add the wcd9378 audio-codec parent node (reset gpio162, l7b/l8b/bob
supplies, 1.8 V micbias x3, rx/tx slave phandles), tx/rx port mappings
on the SoundWire slave nodes (ADC1/2/3 on device ports 1/2/3 all mapped
to master port 1, per the downstream volcano tx_swr_ch_map), the WCD
Capture dai-link on TX_CODEC_DMA_TX_3 and the capture audio-routing
(TX SWR_INPUTn inputs - the milos TX macro is a v9.2 variant, not the
SWR_ADCn naming qcm6490 uses).

The vreg_l8b regulator-always-on DTB hack is obsolete: the codec node
now holds vdd-buck.
