Subject: [PATCH v2 0/4] Add and enable the panel

This patch series adds support for the Visionox RM692E5 panel, which is
used on the Nothing Phone (1) and then adds it to the DTS.

Before integrating the panel into the DTS, we update the DSI code to
allow bits-per-component (bpc) values of 10 and 12, since the Visionox
RM692E5 panel operates at 10 bpc.

This has been tested and does not cause any problems (corruptions,
artifacts, etc.)

Changes in v2:
- Patch 1: Add Reviewed-by tag from (Rob Herring (Arm)).
- Patch 2: Remove extra braces in the for loop of the *_get_modes()
function and use ret in the *_prepare() function. (Neil Armstrong)
- Patch 3: Use switch-case to check the bits-per-component value instead
of removing the guard entirely. (Dmitry Baryshkov & Marijn Suijten)
- Patch 3: Add Reviewed-by tag from Dmitry Baryshkov.
- Patch 4: Remove the zero from the panel label and remove the display
property in the SimpleFB node. (Konrad Dybcio)
- Patch 4: Add Reviewed-by tag from Konrad Dybcio.
