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.

- * fb_get_mode - calculates video mode using VESA GTF
- * @flags: if: 0 - maximize vertical refresh rate
- *             1 - vrefresh-driven calculation;
- *             2 - hscan-driven calculation;
- *             3 - pixelclock-driven calculation;
- * @val: depending on @flags, ignored, vrefresh, hsync or pixelclock
- * @var: pointer to fb_var_screeninfo
- * @info: pointer to fb_info
- *
- * DESCRIPTION:
- * Calculates video mode based on monitor specs using VESA GTF.
- * The GTF is best for VESA GTF compliant monitors but is
- * specifically formulated to work for older monitors as well.
- *
- * If @flag==0, the function will attempt to maximize the
- * refresh rate.  Otherwise, it will calculate timings based on
- * the flag and accompanying value.
- *
- * If FB_IGNOREMON bit is set in @flags, monitor specs will be
- * ignored and @var will be filled with the calculated timings.
- *
- * All calculations are based on the VESA GTF Spreadsheet
- * available at VESA's public ftp (http://www.vesa.org).
- *
- * NOTES:
- * The timings generated by the GTF will be different from VESA
- * DMT.  It might be a good idea to keep a table of standard
- * VESA modes as well.  The GTF may also not work for some displays,
- * such as, and especially, analog TV.
- *
- * REQUIRES:
- * A valid info->monspecs, otherwise 'safe numbers' will be used.
