video: move fbdev to drivers/video/fbdev

The drivers/video directory is a mess. It contains generic video related
files, directories for backlight, console, linux logo, lots of fbdev
device drivers, fbdev framework files.

Make some order into the chaos by creating drivers/video/fbdev
directory, and move all fbdev related files there.

No functionality is changed, although I guess it is possible that some
subtle Makefile build order related issue could be created by this
patch.

- * Created      : Thu Sep 23 18:17:43 1999, hmallat
- * Last modified: Tue Nov  2 21:19:47 1999, hmallat
- *
- * I2C part copied from the i2c-voodoo3.c driver by:
- * Frodo Looijaard <frodol@dds.nl>,
- * Philip Edelbrock <phil@netroedge.com>,
- * Ralph Metzler <rjkm@thp.uni-koeln.de>, and
- * Mark D. Studebaker <mdsxyz123@yahoo.com>
- *
- * Lots of the information here comes from the Daryll Strauss' Banshee
- * patches to the XF86 server, and the rest comes from the 3dfx
- * Banshee specification. I'm very much indebted to Daryll for his
- * work on the X server.
- *
- * Voodoo3 support was contributed Harold Oga. Lots of additions
- * (proper acceleration, 24 bpp, hardware cursor) and bug fixes by Attila
- * Kesmarki. Thanks guys!
- *
- * Voodoo1 and Voodoo2 support aren't relevant to this driver as they
- * behave very differently from the Voodoo3/4/5. For anyone wanting to
- * use frame buffer on the Voodoo1/2, see the sstfb driver (which is
- * located at http://www.sourceforge.net/projects/sstfb).
- *
- * While I _am_ grateful to 3Dfx for releasing the specs for Banshee,
- * I do wish the next version is a bit more complete. Without the XF86
- * patches I couldn't have gotten even this far... for instance, the
- * extensions to the VGA register set go completely unmentioned in the
- * spec! Also, lots of references are made to the 'SST core', but no
- * spec is publicly available, AFAIK.
- *
- * The structure of this driver comes pretty much from the Permedia
- * driver by Ilario Nardinocchi, which in turn is based on skeletonfb.
- *
- * TODO:
- * - multihead support (basically need to support an array of fb_infos)
- * - support other architectures (PPC, Alpha); does the fact that the VGA
- *   core can be accessed only thru I/O (not memory mapped) complicate
- *   things?
- *
- * Version history:
- *
- * 0.1.4 (released 2002-05-28)	ported over to new fbdev api by James Simmons
- *
- * 0.1.3 (released 1999-11-02)	added Attila's panning support, code
- *				reorg, hwcursor address page size alignment
- *				(for mmapping both frame buffer and regs),
- *				and my changes to get rid of hardcoded
- *				VGA i/o register locations (uses PCI
- *				configuration info now)
- * 0.1.2 (released 1999-10-19)	added Attila Kesmarki's bug fixes and
- *				improvements
- * 0.1.1 (released 1999-10-07)	added Voodoo3 support by Harold Oga.
- * 0.1.0 (released 1999-10-06)	initial version
- *
