Add tilcdc_crtc_atomic_check(). Checks the display mode validity and
the presence of the mandatory primary plane.
The drm_crtc_helper_funcs mode_fixup() callback is left untouched and
the check function does no try to do its job on purpose, despite what
the mode_fixup() callback's documentations suggests.
The plane's check() callback needs to set drm_crtc_state's
->mode_changed to true if the pixel format for the framebuffer
changes. Because of this drm_mode_config_funcs atomic_check() callback
needs to call drm_atomic_helper_check_modeset() once more after it has
called drm_atomic_helper_check_planes(). If the fixing of the
adjusted_mode would be done in drm_crtc_helper_funcs atomic_check()
callback, it would get over written by the extra
drm_atomic_helper_check_modeset() call.

Add tilcdc_crtc_mode_set_nofb(). The mode_set_nofb() semantics do not
fit well to LCDC, because of the mandatory framebuffer. However, when
the primary plane is required in the check phase, it and the
framebuffer can be found from the atomic state struct.

Add dummy primary plane implementation. LCDC does not really have
planes, only simple framebuffer that is mandatory. This primary plane
implementation has the necessary checks for implementing simple
framebuffer trough DRM plane abstraction. For setting the actual
framebuffer the implementation relies on a CRTC side function.

Make tilcdc_crtc_page_flip() work if crtc is not yet on. The plane
commit sometimes comes before crtc is turned on. The new framebuffer
should be set to scanout also in that case, so that it is there when
crtc is turned on at the end of the commit phase.

Fix tilcdc component master unloading. If a subcomponent module
(tda998x in this case) is unloaded before its master (tilcdc in this
case), it calls drm_put_dev() and it should not be called again by
the master when its module is unloaded. However component_master_del()
must still be called and the check if the drm_put_dev() has been
called must be in component_master_ops unbind() callback, not in
platform_driver remove() callback.

To properly implement atomic w/ runtime pm, we move
drm_atomic_helper_commit_modeset_enables() above
drm_atomic_helper_commit_planes() to ensure CRTCs are enabled before
modifying plane registers, and set active_only to true to filter out
plane update notifications when the CRTC is disabled.
According to the document from linux kernel:
Set the active_only parameters to true in order not to receive plane
update notifications related to a disabled CRTC. This avoids the need
to manually ignore plane updates in driver code when the driver and/or
hardware can't or just don't need to deal with updates on disabled
CRTCs, for example when supporting runtime PM.

drm_plane_helper_check_state() since we have a plane state.
This also eliminates the double clipping the driver was doing
in both check and commit phases). And it should fix src coordinate
addr adjustement. Previously the driver was expecting negative dst
coordinates after clipping, which is not going happen, so any clipping
induced addr adjustment simply didn't happen. Neither did the driver
respect any user configured src coordinates, so panning and such would
have been totally broken. It should be all good now.
