Subject: 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.

- * Layout is based on skeletonfb.c by James Simmons and Geert Uytterhoeven.

- * This driver is written to be used with the Hecuba display controller
- * board, and tested with the EInk 800x600 display in 1 bit mode.
- * The interface between Hecuba and the host is TTL based GPIO. The
- * GPIO requirements are 8 writable data lines and 6 lines for control.
- * Only 4 of the controls are actually used here but 6 for future use.
- * The driver requires the IO addresses for data and control GPIO at
- * load time. It is also possible to use this display with a standard
- * PC parallel port.
- *
- * General notes:
- * - User must set dio_addr=0xIOADDR cio_addr=0xIOADDR c2io_addr=0xIOADDR
