This is a batch of fixes and improvements for the phy-meson8b-usb2
driver:
- convert the existing dt-bindings to json-schema and add a fallback
  compatible string which is already in existing .dtsi files
- differentiate between Meson8 and Meson8m2 using a new compatible
  string for the latter
- simplify the code by using a MMIO regmap
- set / unset the IDDQ and ACA enable bits depending on the operating
  mode (and for the latter also the compatible string)

I suggest that all of these are applied to -next because we will need a
separate .dts patch (which I already have prepared) to use the new
Meson8m2 compatible string in meson8m2.dtsi. Otherwise we will be
changing behavior in patch #4, because meson8m2.dtsi currently inherits
the Meson8 compatible string.
The number of actual Meson8 users is very small (I only know one case),
so keeping Meson8m2 working is more important to me (because I know
several users with boards that have a Meson8m2 SoC).


Changes since v1 at [0]:
- added Thomas' Tested-bys (thank you!)
- also switched to the correct email address of Thomas for Reported-by
  in patch #4
- added two more spaces for the indentation of the compatible "enum",
  fixed the indentation (was three instead of two spaces) of the
  phy-supply property and added additionalProperties: false. All
  spotted in patch #1 by Rob - thank you!
- added Rob's Acked-by to patch #2 (thank you!), after fixing up the
  indentation to also use four spaces (same as in patch #1)

Applied all, thanks
