arm64: dts: qcom: milos-fairphone-fp6: enable SoundWire buses with WCD9378 slaves

Browse source 
Enable the RX (swr1) and TX (swr2) SoundWire controllers and describe
the two WCD9378 codec slave devices, as enumerated on hardware:
unique-id 4 on the RX bus, unique-id 3 on the TX bus, SoundWire id
sdw20217011000 (mfg 0x0217, part 0x0110). A firmware description is
required for the sdw core to bind a driver since dynamically enumerated
devices are visible but not bindable.

WIP: the codec node set is minimal (no port mappings, no codec parent
node yet); grows with the wcd9378 driver.
