[v3,0/5] Replace hibmc code with generic implmentation

Message

The patch set replaces code in hibmc with generic implementation.
Version 3 of the patchset only adds fixes. I'm reposting the whole
thing for possible testers.

Patches 1 to 4 replace fbdev emuation, framebuffer and creation of
dumb buffers with respective code from DRM helpers. Patch 5 adds an
additional interface to debugfs that displays the allocated and free
areas in video memory.

The patches have only been compile-tested. Further testing is
appreciated.

v3:
	* only do power-of-2 test if pitch_align is given
	* update mgag200 for changes to drm_gem_vram_fill_create_dumb()
v2:
	* split [3/4] into vram and hibmc changes
	* verify that pitch_align is power of two
