regulator: p3h2x4x: Add driver for on-die regulators in NXP P3H2x4x i3c hub

This commit introduces a driver for the on-die regulators of the NXP P3H2x4x
i3c hub family. It registers the regulators via the MFD framework and exposes
them to the regulator subsystem.

[Severity: Low]
Does this driver-specific header need to be placed in the global
include/linux/mfd/ directory? 

According to MFD subsystem guidelines, driver-specific header files that are
only used by the parent and its immediate children should be kept local to
drivers/mfd/ rather than cluttering the global include space. The commit
message explicitly notes that this header is "used only by the parent and
its children".
