linux-postmarketos-qcom-sc7180: Backport sound support for Aspire 1 (MR 4648)

Subject: [PATCH 07/17] arm64: dts: qcom: sc7180: Split up TF-A related PSCI
configuration
When initially submitted, the sc7180 support only targeted CROS devices
that make use of alternative TF-A firmware and not the official Qualcomm
firmware. The PSCI implementations in those firmwares differ however so
devices that use qcom firmware, like WoA laptops such as aspire1 need
different setup.
This commit adjusts the SoC dtsi to the OSI mode PSCI setup, common to
the Qualcomm firmware and introduces new sc7180-firmware-tfa.dtsi that
overrides the PSCI setup for the PC mode and uses TF-A specific
psci-suspend-param. This dtsi is added to all boards that appear to use
TF-A.
