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)
    from Nicolas Saenz Julienne
