Since commit 3c74682637e6 ("drm/msm/mdp4: move resource allocation to
the _probe function") the mdp4_kms data is allocated during probe. It is
an error to destroy it during mdp4_kms_init(), as the data is still
referenced by the drivers's data and can be used later in case of probe
deferral.
MSM display drivers provide kms structure allocated during probe().
Don't clean up priv->kms field in case of an error. Otherwise probe
functions might fail after KMS probe deferral.

Only TTM-based drivers use fbdev-generic. Rename it to fbdev-ttm and
change the symbol infix from _generic_ to _ttm_. Link the source file
into TTM helpers, so that it is only build if TTM-based drivers have
been selected. Select DRM_TTM_HELPER for loongson.

Add an fbdev emulation for SHMEM-based memory managers. The code is
similar to fbdev-generic, but does not require an additional shadow
buffer for mmap(). Fbdev-shmem operates directly on the buffer object's
SHMEM pages. Fbdev's deferred-I/O mechanism updates the hardware state

Add a callback for drivers to provide framebuffer pages to fbdev's
deferred-I/O helpers. Implementations need to acquire a reference on
the page before returning it. Returning NULL generates a SIGBUS
signal.
This will be useful for DRM's fbdev emulation with GEM-shmem buffer
objects.

Rewrite some docs that are not up-to-date any longer. Remove the TODO
item for fbdev-generic conversion, as the helper has been replaced. Make
documentation for DMA, SHMEM and TTM emulation available.
