ARM: late SoC changes for 6.9

These are changes that for some reason ended up not making it into the
 first four branches but that should still make it into 6.9:
 
  - A rework of the omap clock support that touches both drivers and
    device tree files
 
  - The reset controller branch changes that had a dependency on late
    bugfixes. Merging them here avoids a backmerge of 6.8-rc5 into the
    drivers branch
 
  - The RISC-V/starfive, RISC-V/microchip and ARM/Broadcom devicetree
    changes that got delayed and needed some extra time in linux-next
    for wider testing.
