[PATCH v1 7/8] arm64: dts: qcom: maili-mtp: enable audio playback and capture

[Prasad Kumpatla <prasad.kumpatla@oss.qualcomm.com>]

Wire up the audio use cases on the Maili MTP board on top of the LPASS
nodes added to the SoC dtsi, mirroring the Maili QRD board.

Add the sound card with the TDM playback, WCD playback/capture and VA
DMIC capture DAI links and the associated audio routing. Describe the
WCD9395 codec, enable the RX and TX SoundWire controllers with their
WCD RX/TX satellite ports, and add the WSA8855 speaker amplifier on
i2c3. Configure the VA macro DMIC supply and the required TLMM pin
states (WCD reset, WSA IRQ, WSA shutdown).

The MTP and QRD boards share the same SoC and PMIC rails, so the same
regulators (vreg_l2d_1p8, vreg_l4g_1p2, vreg_l15b_1p8, vreg_bob1,
vreg_l1g_1p2, vreg_l10b_1p8) and the pmh0110_f_e0_gpios speaker
shutdown GPIO from the shared pmh0110-kaanapali.dtsi apply unchanged.
