Add support to boot up mainline kernel on the QCM6490-based Fairphone 5
smartphone.
These patches only cover a part of the functionality brought up on
mainline so far, with the rest needing larger dts and driver changes or
depend on patches that are not yet merged. I will work on sending those
once these base patches here have settled.
Since QCM6490, like SC7280 are 'yupik' in the vendor-provided kernel, we
can base the dts on it and leverage existing support. Though current
sc7280 support mostly assumes ChromeOS devices which have a different
TrustZone setup, so we need to move some ChromeOS-specific bits to the
sc7280-chrome-common.dtsi file to make it boot on a standard TZ board.
Depends on (just for the #include in sc7280.dtsi):

Changes in v2:
- Add comments why nodes in sc7280.dtsi get disabled (Konrad)
- Mark more nodes in sc7280.dtsi as reserved
- Don't allow writing qfprom when (optional) clock isn't found
- Device dts changes:
- Stylistic changes in device dts
- Remove qcom,msm-id & qcom,board-id properties
- Add regulator-initial-mode
- Pick up tags
- Drop patch 03 "arm64: dts: qcom: sc7280: Move qfprom clock to
chrome-common", it's actually not needed with qfprom-clock-optional
patch
- Drop patch 07 "dt-bindings: arm: qcom,ids: Add SoC ID for QCM6490",
patch 08 "soc: qcom: socinfo: Add SoC ID for QCM6490" and patch 09
"cpufreq: Add QCM6490 to cpufreq-dt-platdev blocklist", all applied.
