ARM: SoC fixes for 5.19

A number of fixes have accumulated, but they are largely for
harmless issues:

 - Several OF node leak fixes

 - A fix to the Exynos7885 UART clock description

 - DTS fixes to prevent boot failures on TI AM64 and J721s2

 - Bus probe error handling fixes for Baikal-T1

 - A fixup to the way STM32 SoCs use separate dts files for
   different firmware stacks

 - Multiple code fixes for Arm SCMI firmware, all dealing with
   robustness of the implementation

 - Multiple NXP i.MX devicetree fixes, addressing incorrect
   data in DT nodes

 - Three updates to the MAINTAINERS file, including Florian
   Fainelli taking over BCM283x/BCM2711 (Raspberry Pi)
