[PATCH v3 2/8] arm64: dts: qcom: shikra: Add QAIF CPU node for audio

[Mohammad Rafi Shaik]

Add the QAIF CPU endpoint in shikra.dtsi so board files can connect LPASS
front-end links to backend codecs.

Describe the MMIO region, interrupt, IOMMU mapping and required clocks for
the QAIF block. Keep the node disabled at SoC level; board dts files enable
and consume it in subsequent patches.
