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

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.
