[PATCH 6.12 25/55] arm64: dts: ti: k3-j721e-sk: Add requiried voltage supplies for IMX219

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Yemike Abhilash Chandra <y-abhilashchandra@ti.com>

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.
