drm/msm: Implement mmap as GEM object function
Moving the driver-specific mmap code into a GEM object function allows
for using DRM helpers for various mmap callbacks.
The respective msm functions are being removed. The file_operations
structure fops is now being created by the helper macro
DEFINE_DRM_GEM_FOPS().
v2:
* rebase onto latest upstream
* remove declaration of msm_gem_mmap_obj() from msm_fbdev.c
