drm: Move client code to clients/ subdirectory 



Just move some files around to keep source code well organized. Plus
fix a type in the help text of CONFIG_DRM_FBDEV_LEAK_PHYS_SMEM. No
functional changes.

	  This affects, not only, Amlogic, Allwinner or Rockchip devices

	  with ARM Mali GPUs using an userspace Blob.

	  This option is not supported by upstream developers and should be

	  Please send any bug reports when using this to your proprietary

	  software vendor that requires this.



	  If in doubt, say "N" or spread the word to your closed source

	  library vendor.
