arm64: dts: ti: k3-am62x: Add required voltage supplies for OV5640

Browse Source 
The device tree overlay for OV5640 requires following voltage
supplies as mentioned in the table 8-3 of the data-sheet [1].

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.
