Add regulator devices for PMIC regulators managed via VRM and XOB
RPMh accelerators.

A few notes here:
- Regulators are added directly to the board file.  While it's true
  that this will mean a bunch of copy/pasting for other boards that
  are very similar to MTP, this is probably the right call since
  boards could make changes to the way these regulators are hooked up
  and trying to find a way to avoid duplication will result in some
  confusing node overrides.
- Regulators are always given labels based on the schematic.  If there
  is more than one logical name on the schematic for the same rail the
  all of these secondary names are also listed and should be referred
  to as appropriate.
- Regulators all default to HPM mode with the assumption that if a
  rail is being provided to a driver that doesn't specify the needed
  current that we'll at least be correct.

NOTE: This patch is loosely based on one originally shared to me by
David Collins.

I would suggest not specifying any of these regulator parent supplies in
device tree.  RPMh will be enforcing all regulator parent-child
dependencies.  Therefore, handling the dependencies in Linux is redundant.
 It will result in additional RPMh requests as well as more time spent in
regulator framework calls.  Overall, it will lead to slightly lower
performance.  Note that while specifying the parent supplies results in
less efficient runtime behavior, it is not technically wrong so you could
keep them in place if you prefer.

Take care,
David

Interesting.  ...so RPMh will automatically turn on parent regulators
when their children are enabled (assuming that the parent regulator is
also RPMh controlled)?

Personally I'd still prefer to see Linux managing its own state and
relying less on RPMh-automatic stuff, but I'd defer to Bjorn / Andy
(or others) to override me.

Yes, exactly.  RPMh also ensures that the voltage of a parent regulator is
sufficient to meet minimum headroom voltage requirements of all
subregulated child regulators.
