ARM: SoC fixes for 6.1, part 2

Browse Source 
There are not a lot of important fixes for the soc tree yet this
 time, but it's time to upstream what I got so far:
 
  - DT Fixes for Arm Juno and ST-Ericsson Ux500 to add missing critical
    temperature points
 
  - A number of fixes for the Arm SCMI firmware, addressing correctness
    issues in the code, in particular error handling and resource leaks.
 
  - One error handling fix for the new i.MX93 power domain driver
 
  - Several devicetree fixes for NXP i.MX6/8/9 and Layerscape chips,
    fixing incorrect or missing DT properties for MDIO controller nodes,
    CPLD, USB and regulators for various boards, as well as some
    fixes for DT schema checks.
