dt-bindings: i3c: Add NXP P3H2x4x i3c-hub support
    
This patch adds device tree bindings for the NXP P3H2x4x multiport I3C hub
family. These devices connect to a host via I3C/I2C/SMBus and allow
communication with multiple downstream peripherals.

[Severity: Low]
Should the top-level compatible property be included in this required list?

Standard device tree binding schemas expect the top-level compatible property
to be explicitly listed in the required array for standalone device nodes.
Although dt-schema matches the node by compatible string, omitting it from the
required list allows a node to theoretically pass validation without one if
referenced through other means.
