arm64: dts: ti: k3-am625-beagleplay: Add required voltage supplies for OV5640

The device tree overlay for OV5640 requires following voltage
supplies:

AVDD-supply: Analog voltage supply, 2.8 volts
DOVDD-supply: Digital I/O voltage supply, 1.8 volts
DVDD-supply: Digital core voltage supply, 1.5 volts

Add them in the overlay.
