soc: driver updates for 6.14

These are changes to SoC specific drivers and DT bindings that don't have
 a separate subsystem tree, or that get grouped here for simplicity.
 Nothing out of the ordinary for the 6.14 release here:
 
  - Most of the updates are for Qualcomm specific drivers, adding support
    for additional SoCs in the exssting drivers, and support for wrapped
    encryption key access in the SCM firmware.
 
  - The Arm SCMI firmware code gains support for having multiple
    instances of firmware running, and better module auto loading.
 
  - A few minor updates for litex, samsung, ti, tegra, mediatek, imx and
    renesas platforms.
 
  - Reset controller updates for amlogic, to add support for the A1 soc
    and clean up the existing code.
 
  - Memory controller updates for ti davinci aemif, refactoring the code
    and adding a few interfaces to other drivers.
