[PATCH net-next 2/4] dt-bindings: net: pse-pd: realtek,pse-mcu: add VMAIN supply

[Jonas Jelonek]

Describe the VMAIN supply at the MCU controller level. The rail feeds the
PoE subsystem as a whole rather than an individual PI. Its regulator power
budget defines the aggregate limit programmed into the MCU.

Require a finite regulator power budget dedicated to this MCU, representing
the PoE power allocation of the system.
