    mediatek: dts: mt7988a: wire-up mediatek,pio for PHY LEDs
    
    The PHY driver needs to read a register containing the values of the
    bootstrap pins (which happen to be the PHY LEDs) to determine the LED
    polarities. Allow regmap access to first pinctrl bank by adding the
    'syscon' compatible, and reference the pinctrl in the MDIO bus where
    the PHY driver will look for it.
