arm64: dts: ti: k3-j721e-sk: Add requiried voltage supplies for IMX219

commit c6a20a250200da6fcaf80fe945b7b92cba8cfe0f upstream.

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). Add the corresponding voltage supply definitions to
avoid dtbs_check warnings.
