ARM: SoC fixes for v5.15

This is a larger than normal update for Arm SoC specific code, most
of it in device trees, but also drivers and the omap and at91/sama7
platforms:

 - There are four new entries to the MAINTAINERS file: Sven Peter and
   Alyssa Rosenzweig for Apple M1, Romain Perier for Mstar/sigmastar,
   and Vignesh Raghavendra for TI K3

 - Build fixes to address randconfig warnings in sharpsl, dove, omap1,
   and qcom platforms as well as the  scmi and op-tee subsystems

 - Regression fixes for missing CONFIG_FB and other options for several
   defconfigs

 - Several bug fixes for the newly added Microchip SAMA7 platform,
   mostly regarding power management

 - Missing SMP barriers to protect accesses to SCMI virtio device

 - Regression fixes for TI OMAP, including a boot-time hang on am335x.

 - Lots of bug fixes for NXP i.MX, mostly addressing incorrect settings
   in devicetree files, and one revert for broken suspend.

 - Fixes for ARM Juno/Vexpress devicetree files, addressing a couple
   of schema warnings.

 - Regression fixes for qualcomm SoC specific drivers and devicetree
   files, reverting an mdt_loader change and at least pastially
   reverting some of the 5.15 DTS changes, plus some minor bugfixes
