Subject: [PATCH AUTOSEL 5.9 11/35] ARM: dts: mmp3: Add power domain for the camera

From: Lubomir Rintel <lkundrak@...sk>

[ Upstream commit 202f8e5c4975a95babf3bcdfb2c18952f06b030a ]

The camera interfaces on MMP3 are on a separate power island that needs
to be turned on for them to operate and, ideally, turned off when the
cameras are not in use.

This hooks the power island with the camera interfaces in the device
tree.
