[PATCH] fbcon: Console Rotation - Add ability to control rotation via sysfs

Add ability to set rotation via sysfs.  The attributes are located in
/sys/class/graphics/fb[n] and accepts 0 - unrotated; 1 - clockwise; 2 - upside
down; 3 - counterclockwise.

The attributes are:

con_rotate (r/w) -   set rotation of the active console
con_rotate_all (w) - set rotation of all consoles
rotate (r/w) -       set rotation of the framebuffer, if supported.
Currently, none of the drivers support this.

This is probably temporary, since con_rotate and con_rotate_all are
console-specific and has no business being under the fb device.  However,
until the console layer acquires it's own sysfs class, these attributes will
temporarily reside here.
