  1. drivers: regulator: Add NXP VREF driver

    Add binding, include header, and driver for NXP VREF IP block.
    
    NXP VREF is an internal voltage reference generator on some SOCs
    that fits well with the regulator API in zephyr.

  3. dts: bindings: lpadc: Add regulator phandle prop

    Add phandle prop to reference any regulator that must
    be enabled in order for the LPADC to function as intended.
    
    Change LPADC driver to use this property if present.
    
    LPADC on LPC55S36 depends on VREF peripheral, enable for this platform.
