[PATCH 3/5] arm64: dts: ti: k3-j721e-sk: Fix dtbs_check warnings in IMX219 overlay

[Yemike Abhilash Chandra <y-abhilashchandra@ti.com>]

The device tree bindings mandate three regulator nodes for the IMX219
sensor: VANA (analog), VDIG (digital core), and VDDL (digital I/O). Add the
necessary regulator nodes in the device tree overlay and also the device
tree bindings do not include a clock-names property. Remove the incorrectly
added clock-names entry to avoid dtbs_check warnings.

Fixes: f767eb918096 ("arm64: dts: ti: k3-j721e-sk: Add overlay for IMX219")
