Subject: [PATCH 1/2] media: dt-bindings: add flip properties

There are cameras containing a mirror on their optical path e. g. when
mounted upside down.

Introduce two options to change the device's flip property via device tree.

As there is already support for the panel-common driver [1], add it for cameras as well.

[1] commit 3c0ecd83eee9 ("dt-bindings: display: panel: Move flip properties to panel-common")
