We revisit this change. Previous we added the different hotspots together
just before programming the device, but that makes the plane atomic state
incompatible with what's actually in the device.
So add a way for the only legacy ioctl that doesn't support cursor hotspots
to add the device internal legacy hotspots into the atomic plane state.

Mostly straight copy-and-paste from upstream, with the following
notable changes
* Added #undef CONFIG_DEBUG_FS in drmP.h to exclude all debugfs code
* Minor updates to a few vmwgfx files due to API change
* Carried over from the v4.11 update: Skipped update to drm_mm and
drm_vma_manager because the switch to using interval tree makes
porting difficult
* Added #include <linux/highuid.h> to drm_ioctl.c to make CentOS
build
* Rolled in [Commit 3bacf4361cd0: drm/vmwgfx: Fix fbdev emulation
using legacy functions]
* Updated vmwgfx code to match upstream v4.12 code

* Skipped update to drm_mm and drm_vma_manager because the switch to

* Added memdup_user_nul(), but replaced kmalloc_track_caller() with
kmalloc() due to a compilation error.
* Removed building and usage of debugfs_crc
* VMWGFX_COMPAT_NO_VAF no longer seems to be required
* Tested on
