[RESEND,0/3] drm/{exynos,xen}: Implement gem_prime_mmap with drm_gem_prime_mmap()

Message

(Resending the patchset from [1]. Most drivers have already been updated and
only two drivers are left.)

Replace all remaining implementations of struct drm_driver.gem_prime_mmap
with use drm_gem_prime_mmap(). For each affected driver, put the mmap code
into struct drm_gem_object_funcs.mmap. With the latter change in place,
create struct file_operations via DEFINE_DRM_GEM_FOPS().

As next steps, drivers can be converted to use drm_gem_prime_mmap() and
drm_gem_mmap() (e.g., Tegra). The default mmap code in drm_gem_prime_mmap()
can be pushed into affected drivers or a helper function. The gem_prime_mmap
hook can probably be removed at some point.
