Pull SoC driver updates from Arnd Bergmann:
 "The highlights for the driver support this time are

   - Qualcomm platforms gain support for the Qualcomm Secure Execution
     Environment firmware interface to access EFI variables on certain
     devices, and new features for multiple platform and firmware
     drivers.

   - Arm FF-A firmware support gains support for v1.1 specification
     features, in particular notification and memory transaction
     descriptor changes.

   - SCMI firmware support now support v3.2 features for clock and DVFS
     configuration and a new transport for Qualcomm platforms.

   - Minor cleanups and bugfixes are added to pretty much all the active
     platforms: qualcomm, broadcom, dove, ti-k3, rockchip, sifive,
     amlogic, atmel, tegra, aspeed, vexpress, mediatek, samsung and
     more.

     In particular, this contains portions of the treewide conversion to
     use __counted_by annotations and the device_get_match_data helper"
