drm: hide legacy drivers with CONFIG_DRM_LEGACY 



Lets move forward and hide the remaining DRI1 drivers behind a config
option, so we have a central place to disable them all. Furthermore, we
can provide a clear warning to anyone enabling them.

menuconfig DRM_LEGACY

	bool "Enable legacy drivers (DANGEROUS)"

	depends on DRM

	help

	  Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous

	  APIs to user-space, which can be used to circumvent access

	  restrictions and other security measures. For backwards compatibility

	  those drivers are still available, but their use is highly

	  inadvisable and might harm your system.



	  You are recommended to use the safe modeset-only drivers instead, and

	  perform 3D emulation in user-space.



	  Unless you have strong reasons to go rogue, say "N".
