[PATCH v4 1/2] arm64: dts: qcom: talos: Add GPR node, audio services, and MI2S1 TLMM pins

[Le Qi]

This patch adds the Generic Pack Router (GPR) node together with
Audio Process Manager (APM) and Proxy Resource Manager (PRM)
audio service nodes to the Talos device tree description.

It also introduces MI2S1 pinctrl states for data0, data1, sck,
and ws lines, grouped into a single entry at the SoC-level DTSI
for better reuse and clarity.
