arm64: dts: qcom: sa8775p: add basic PMIC support

From: Bartosz Golaszewski <[email protected]>

This adds support for a number of PMIC functionalities on sa8775p. The PMIC used on the reference board is pm8654au which is another variant of the SPMI PMIC from Qualcomm with an automotive twist.

v2 -> v3:
- add GPIO line names for the PMIC GPIOs on sa8775p-ride
- add missing GPIO chips to the PMIC .dtsi
- add missing thermal zones and alerts
- add regulators (driver support and regulator settings for sa8775p-ride)
- add missing PDC mappings
- squash patches 7 and 8 to avoid adding code without users
- dropped Krzysztof's Ack from patch 3 as it now extends the max number of mappings so most likely needs a second look

v1 -> v2:
- improve DT coding style where needed
- don't disable the power button in PMIC's .dtsi
- add debounce time for pwrkey and resin inputs
- use the official PMIC's name in DT labels
- add reg-names property for the PON node
- add patches that tidy up the dtsi before the PMIC stuff
