Merge branch 'qcom-main' of https://source.denx.de/u-boot/custodians/u-boot-snapdragon

We have been getting a lot more patches from Qualcomm engineers, largely
focusing on IoT, router, and automotive platforms (those with QCS, IPQ,
and SA prefixes specifically).

Quite a variety of changes here:
- Watchdog overflow fix
- Hardcoded fastboot buffer addresses for a few board (hoppefully
  temporary until fastboot is updated to read $fastboot_addr_r)
- Enable memory protection (MMU_MGPROT) for ARCH_SNAPDRAGON
- pinctrl support for the QCS615 soc
- various USB/phy fixes including phy config for msm8996/qcs615
- mmc and i2c clock configuration fixes
- significant fixes for rpmh and regulator drivers
- added config fragment for pixel devices
- sa8775p clock fixes
- support for "flattened" dwc3 DT that recently landed upstream for
  sc7280 (qcs6490) and a few other platforms
