arm64: dts: qcom: sdm845-oneplus-*: add audio devices

Populate the audio devices found on the OnePlus 6 and 6T using the
sdm845-sndcard driver.

Both devices have the earpiece and headphone jack connected to the
WCD9341 codec. The OnePlus 6 uses the MAX98927 speaker codec which is
already supported upstream. The OnePlus 6T uses a currently unsupported
TFA9894 codec.

Two internal microphones are supported, as well as an external headset
mic. Each DAI link is expected to be used for a single device.

Alsa UCM2 configs for this setup can be found here, they are not yet
upstream and include support for call audio which is missing in this
patch
