riscv: dts: starfive: beaglev-starlight: Setup phy reset gpio

The BeagleV Starlight SBC uses a Microchip KSZ9031RNXCA PHY supporting
RGMII-ID which doesn't require any particular setup, other than defining
a reset gpio, as opposed to VisionFive V1 for which the RX internal
delay had to be adjusted.
