drm: allow removal of legacy codepaths (v4.1)
If you don't want the legacy drivers, then lets get rid of all the
legacy codepaths from the core module.
This drop the size of drm.ko for me by about 10%.
380515 7422 4192 392129 5fbc1 ../../drm-next-build/drivers/gpu/drm/drm.ko
351736 7298 4192 363226 58ada ../../drm-next-build/drivers/gpu/drm/drm.ko
v2: drop drm_lock as well, fix some DMA->DRM typos
v3: avoid ifdefs in mainline code
v4: rework ioctl defs
v4.1: fix nouveau Kconfig
