Improve the wkup_m3_ipc driver to better support the TI Wakeup Cortex M3 
device found on TI AM33xx and AM43xx SoCs.

This series derives from these commits in the ti-linux-5.10.y branch of
the TI Linux repo [1]:

  6ab4eff1034b ("remoteproc: move rproc_da_to_va declaration to remoteproc.h")
  2a9be39a26f7 ("dt-bindings: wkup_m3_ipc: Add vtt toggling bindings")
  c65263f9e12c ("wkup_m3_ipc: Add support for toggling VTT regulator")
  5c6c821803e1 ("dt-bindings: wkup_m3_ipc: Add ti,io-isolation property")
  196c46f7577d ("wkup_m3_ipc: Add support for IO Isolation")
  c28acc847e5d ("soc: ti: wkup_m3_ipc: Add support for i2c voltage scaling")
  a4f9ef4ab5ca ("ARM: dts: am437x-gp-evm: Enable wkup_m3 control of IO isolation")
  94de756f1771 ("ARM: dts: am33xx: Add scale data fw to wkup_m3_ipc node")
  b7ae4b063793 ("ARM: dts: am43xx: Add scale data fw to wkup_m3_ipc node")
  451ec7871ae7 ("soc: ti: wkup_m3_ipc: Add debug option to halt m3 in suspend")

Minor changes have been made to some patches to resolve conflicts and 
to split i2c voltage scaling dt-bindings into separate patch.
