[PATCH v4 3/3] arm64: dts: qcom: shikra: Add support for AudioCoreCC and AudioCoreCSR nodes

[Imran Shaik]

Add support for Audio Core Clock Controller (AudioCoreCC) and Audio Core
CSR nodes on Qualcomm Shikra SoC. The Audio Core Clocks and Resets support
differs across Shikra variants based on Audio subsystem enablement as
follows:
- CQM variant: The QAIF driver runs on HLOS, hence both clocks and resets
are required to be supported on HLOS.
- CQS variant: The QAIF driver runs on the Modem, and required clocks are
handled on Modem, so from HLOS only resets are needed.
- IQS variant: no soundwire codes, hence no clocks/resets are needed.
