Subject: [PATCH v5 1/9] arm64: dts: qcom: qcs6490-audioreach: Add gpr node

From: Mohammad Rafi Shaik <quic_mohs@...cinc.com>

Add GPR(Generic Pack router) node along with
APM(Audio Process Manager) and PRM(Proxy resource
Manager) audio services.

A new qcs6490-audioreach.dtsi file has been added to
update AudioReach specific device tree configurations.
The existing audio nodes in sc7280.dtsi, which were designed
for the ADSP Bypass solution. The audio nodes now being updated
in qcs6490-audioreach.dtsi to support the ADSP-based AudioReach
architecture.
