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.

- * This driver consists of two parts. The first part (intelfbdrv.c) provides
- * the basic fbdev interfaces, is derived in part from the radeonfb and
- * vesafb drivers, and is covered by the GPL. The second part (intelfbhw.c)
- * provides the code to program the hardware. Most of it is derived from
- * the i810/i830 XFree86 driver. The HW-specific code is covered here
- * under a dual license (GPL and MIT/XFree86 license).

- * Changes:
- * 01/2003 - Initial driver (0.1.0), no mode switching, no acceleration.
- * This initial version is a basic core that works a lot like
- * the vesafb driver. It must be built-in to the kernel,
- * and the initial video mode must be set with vga=XXX at
- * boot time. (David Dawes)
- *
- * 01/2003 - Version 0.2.0: Mode switching added, colormap support
- * implemented, Y panning, and soft screen blanking implemented.
- * No acceleration yet. (David Dawes)
- *
- * 01/2003 - Version 0.3.0: fbcon acceleration support added. Module
- * option handling added. (David Dawes)
- *
- * 01/2003 - Version 0.4.0: fbcon HW cursor support added. (David Dawes)
- *
- * 01/2003 - Version 0.4.1: Add auto-generation of built-in modes.
- * (David Dawes)
- *
- * 02/2003 - Version 0.4.2: Add check for active non-CRT devices, and
- * mode validation checks. (David Dawes)
- *
- * 02/2003 - Version 0.4.3: Check when the VC is in graphics mode so that
- * acceleration is disabled while an XFree86 server is running.
- * (David Dawes)
- *
- * 02/2003 - Version 0.4.4: Monitor DPMS support. (David Dawes)
- *
- * 02/2003 - Version 0.4.5: Basic XFree86 + fbdev working. (David Dawes)
- *
- * 02/2003 - Version 0.5.0: Modify to work with the 2.5.32 kernel as well
- * as 2.4.x kernels. (David Dawes)
- *
- * 02/2003 - Version 0.6.0: Split out HW-specifics into a separate file.
- * (David Dawes)
- *
- * 02/2003 - Version 0.7.0: Test on 852GM/855GM. Acceleration and HW
- * cursor are disabled on this platform. (David Dawes)
- *
- * 02/2003 - Version 0.7.1: Test on 845G. Acceleration is disabled
- * on this platform. (David Dawes)
- *
- * 02/2003 - Version 0.7.2: Test on 830M. Acceleration and HW
- * cursor are disabled on this platform. (David Dawes)
- *
- * 02/2003 - Version 0.7.3: Fix 8-bit modes for mobile platforms
- * (David Dawes)
- *
- * 02/2003 - Version 0.7.4: Add checks for FB and FBCON_HAS_CFB* configured
- * in the kernel, and add mode bpp verification and default
- * bpp selection based on which FBCON_HAS_CFB* are configured.
- * (David Dawes)
- *
- * 02/2003 - Version 0.7.5: Add basic package/install scripts based on the
- * DRI packaging scripts. (David Dawes)
- *
- * 04/2003 - Version 0.7.6: Fix typo that affects builds with SMP-enabled
- * kernels. (David Dawes, reported by Anupam).
- *
- * 06/2003 - Version 0.7.7:
- * Fix Makefile.kernel build problem (Tsutomu Yasuda).
- * Fix mis-placed #endif (2.4.21 kernel).
- *
- * 09/2004 - Version 0.9.0 - by Sylvain Meyer
- * Port to linux 2.6 kernel fbdev
- * Fix HW accel and HW cursor on i845G
- * Use of agpgart for fb memory reservation
- * Add mtrr support
- *
- * 10/2004 - Version 0.9.1
- * Use module_param instead of old MODULE_PARM
- * Some cleanup
- *
- * 11/2004 - Version 0.9.2
- * Add vram option to reserve more memory than stolen by BIOS
- * Fix intelfbhw_pan_display typo
- * Add __initdata annotations
- *
- * 04/2008 - Version 0.9.5
- * Add support for 965G/965GM. (Maik Broemme <mbroemme@plusserver.de>)
- *
- * 08/2008 - Version 0.9.6
- * Add support for 945GME. (Phil Endecott <spam_from_intelfb@chezphil.org>)
