dtoverlays: Update sensor overlays to use cam1_reg where possible

raspberrypi inclusion
category: feature
bugzilla: 50432

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

Update those overlays that use the regulator framework to use the
new cam1_reg node to control the camera shutdown line, and remove
the firmware workaround nodes.
