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

CI: https://source.denx.de/u-boot/custodians/u-boot-snapdragon/-/pipelines/23474

- UFS support is enabled for SC7280 and SM8150 platforms.
- Qualcomm dt-bindings headers are all dropped in favour of
  dts/upstream.
- The SMMU driver now correctly handles stream ID 0 and is disabled in
  EL2.
- Initial support for capsule updates (using the new dynamic UUIDs) is
  added for the RB3 Gen 2 board alongside a new SCSI backend for DFU.
- CONFIG_PINCONF is enabled in qcom_defconfig.
- The vqmmc supply is now enabled for sdcard support on boards that need
  it.
- A quirk is added for reading GPIOs on the PM8550 PMIC
