This series replaces the dependency on
probing and disables the support for drm_gralloc.

The series has been tested on Qemu+AOSP, where a
virtio gpu was successfully probed for and

Changes since v3:
 - Reduced number of probing return codes
 - Simplified driver vendor check in droid_probe_device()
 - Fixed type with ';' prepended to a if-statement
 - Removed a strlen call

 - Replaced fd == -1 check with < 0
 - Simplified switch+goto statements

Changes since v2:
 - Fixed whitespace issue
 - Diversified return codes from probing functions
 - Switched away from using drmGetDevices2, to iterating over
   /dev/dir/renderD nodes manually

 - Do not rely on libdrm for probing
 - Distinguish between errors and when no drm devices are found

Changes since RFC:
