Remove unnecessary include statements for <drm/drm_plane_helper.h>.
The file contains helpers for non-atomic code and should not be
required by most drivers. No functional changes.

Implement atomic mode setting for both the primary and overlay planes.
This involves:
- Moving the primary plane handling code from CRTC mode setting to
plane handling shared by primary and overlay planes,
- Adding basic CRTC and mode config atomic mode setting ops, which
don't do much yet.

Rename the "plane" member of the shmob_drm_plane subclass structure to

Unify primary and overlay plane allocation:
- Enhance shmob_drm_plane_create() so it can be used to create the
primary plane, too,
- Move overlay plane creation next to primary plane creation.

Now that drm_device is embedded in shmob_drm_device, we can use
a container_of()-based helper to get the shmob_drm_device pointer from
the drm_device, instead of using the deprecated drm_device.dev_private
field.
While at it, restore reverse Xmas tree ordering of local variable
declarations.

According to the comments for drm_universal_plane_init(), the plane
structure should not be allocated with devm_kzalloc().
Fix lifetime issues by using drmm_universal_plane_alloc() instead.

There is no need to call drm_plane_force_disable() from the plane's
.destroy() callback, as the plane should have been disabled already
before. See also commit 3c858a33858baa8c ("drm/plane_helper: don't
disable plane in destroy function") for the generic plane helper case.
After removing this call, shmob_drm_plane_destroy() becomes a simple
wrapper around shmob_drm_plane_destroy(), hence replace it by the
latter.

Improve the table containing hardware information related to the
supported plane formats:
1. Move (part of) the overlay format register settings from multiple
switch() statements spread across the code into the table, like is
already done for the primary plane register settings,
2. Remove the .yuv field, as that information can easily be extracted
from the register settings using a new helper macro,
3. Shrink and move the .bpp field to reduce table size.

When configuring a CHn Source Image Format Register (LDBBSIFR), one
should use the corresponding LDBBSIFR_RPKF_* definition for overlay
planes, not the DDFR_PKF_* definition for the primary plane.
Fortunately both definitions resolve to the same value, so this bug did
not cause any harm.

Merely writing zero to the CHn Source Image Format Register is not
sufficient to disable a plane, as the programmed register value is not
propagated immediately to the current side. This can be seen when using
the -P option of modetest: the extra plane is displayed correctly, but
does not disappear after exit.
Fix this by doing the full update dance using the Blend Control
Register, like is done when enabling the plane.
