soc: fixes for 6.13

Browse Source 
There are three small fixes for the soc tree:
 
  - A devicetee fix for the Arm Juno reference machine, so allow more
    interesting PCI configurations
 
  - A build fix for SCMI firmware on the NXP i.MX platform
 
  - A fix for a race condition in Arm FF-A firmware
