arm64: dts: ti: k3-am62x: Add required voltage supplies for IMX219

Browse Source 
The device tree overlay for the IMX219 sensor requires three voltage
supplies to be defined: VANA (analog), VDIG (digital core), and VDDL
(digital I/O) [1].

Add the corresponding voltage supply definitions in the overlay so
that the same topography as dt-bindings is present in the DT overlay.
