drm/mode: Add user blob-creation ioctl
Add an ioctl which allows users to create blob properties from supplied
data. Currently this only supports modes, creating a drm_display_mode from
the userspace drm_mode_modeinfo.
v2: Removed size/type checks.
Rebased on new patches to allow error propagation from create_blob,
as well as avoiding double-allocation.
