drm/omapdrm: Set VM flags in GEM-object mmap function
Use the mmap callback in struct drm_gem_object_funcs to set the
VM flags. Replace a number of mmap helpers in omapdrm with their
GEM helper counterparts. Generate DRM's file-operations instance
with GEM's DEFINE_DRM_GEM_FOPS.
The omapdrm driver uses DRM's drm_gem_mmap() helper to prepare
the VMA structure. It then modifies the resulting VMA state in
its own helper omap_gem_mmap_obj(). The patch improves this by
setting up the VMA in the mmap callback in drm_gem_object_funcs,
which is called from within drm_gem_mmap().
Omapdrm's omap_gem_mmap() and omap_gem_mmap() can then be removed
from the driver. A call to drm_gem_mmap() is sufficient for the
mmap operation.
Finally, with the omap functions gone, the drivers file_ops in
omapdriver_fops can be generated with DEFINE_DRM_GEM_FOPS, which
sets DRM's default helpers.
v2:
* detailed commit message (Javier)
* do not set VM_PFNMAP
