drm: reorder struct drm_ioctl_desc to save space on 64 bit builds
shrinks drm_ioctl_desc from 24 bytes to 16 bytes by reordering members
to remove padding.
updates DRM_IOCTL_DEF macro to initialise structure members by name to
handle the structure reorder.
The applied patch reduces data used in drm.ko from 10440 to 9032
