The atomic helpers try really hard to not lose track of things,
duplicating enabled tracking in the driver is at best confusing.
Double-enabling or disabling is a bug in atomic helpers.
In the fb_dirty function we can just assume that the fb always exists,
simple display pipe helpers guarantee that the crtc is only enabled
together with the output, so we always have a primary plane around.
Now in the update function we need to be a notch more careful, since
that can also get called when the crtc is off. And we don't want to
upload frames when that's the case, so filter that out too.

Rename the macro to DRM_GEM_CMA_DRIVER_OPS_VMAP to align naming with
SHMEM helpers and drm_gem_cma_prime_import_sg_table_vmap(). An variant of
the macro is provided for drivers that override the default .dumb_create
callback. Adapt drivers to the changes.
v3:
* rename macro to signal implicit vmap on imported buffers
v2:
* provide DRM_GEM_CMA_DRIVER_OPS_WITH_DUMB_CREATE

Allows us to drop the drm_driver.release callback from all
drivers, and remove the mipi_dbi_release() function.
This is made possible by a preceeding patch which added a drmm_
cleanup action to drm_mode_config_init(), hence all we need to do to
ensure that drm_mode_config_cleanup() is run on final drm_device
cleanup is check the new error code for _init().
v2: Explain why this cleanup is possible (Laurent).
v3: Use drmm_mode_config_init() for more clarity (Sam, Thomas)

7/7 drivers agree that's the right choice, let's do this.
This avoids duplicating the same old error checking code over all 7
drivers, which is the motivation here.

They all share mipi_dbi_release so we need to switch them all
together. With this we can drop the final kfree from the release
function.
Aside, I think we could perhaps have a tiny additional helper for
these mipi_dbi drivers, the first few lines around devm_drm_dev_init
are all the same (except for the drm_driver pointer).
