Padding is a new display module on MT8188, it provides ability
to add pixels to width and height of a layer with specified colors.
Due to hardware design, Mixer in VDOSYS1 requires width of a layer
to be 2-pixel-align, or 4-pixel-align when ETHDR is enabled,
we need Padding to deal with odd width.

With the current cleanup flow, we could trigger a NULL pointer
dereference if there is a delayed destruction of a BO with a
system resource that gets executed on drain_workqueue() call,
as we attempt to free a resource using an already released
resource manager.

UMDs (e.g., mesa) can change the power profile as well. E.g., if they want to
capture an SQ trace, etc. It's likely that is the cause.

drm_mode_rmfb performs two operations: drop the FB from the
file_priv->fbs list, and make sure the FB is no longer used on a
plane.
In the next commit an IOCTL which only does so former will be
introduced, so let's split it into a separate function.
No functional change, only refactoring.
Signed
This new IOCTL allows callers to close a framebuffer without
disabling planes or CRTCs. This takes inspiration from Rob Clark's
unref_fb IOCTL [1] and DRM_MODE_FB_PERSIST [2].
User-space patch for wlroots available at [3]. IGT test available
at [4].

Both files pwm-backlight.yaml and led-backlight.yaml contain properties
in common with each other, regarding the brightness levels:
- brightness-levels
- default-brightness-level
These properties can then be moved to backlight/common.yaml.
