regulator: p3h2x4x: Add driver for on-die regulators in NXP P3H2x4x i3c hub
    
The NXP P3H2x4x family integrates on-die regulators alongside I3C hub
functionality. This driver registers the regulators using the MFD
framework and exposes them via the regulator subsystem.

[Severity: Low]
According to the MFD subsystem guidelines, driver-specific header files that
are only used by the parent and its immediate children should not be placed
in the global include/linux/mfd/ directory.

Could p3h2840.h be kept local to drivers/mfd/ instead of being exposed in the
global include path?
