Remove unnecessary dependencies in the include statements of the
header file <linux/fb.h>. Several files throughout the kernel include
the fbdev header, so reducing dependencies positively affects other
subsystems as well. Also fix up corgi-lcd, nouveau and fbtft, which
need backlight.h in some of their source files.

v3:
	* include backlight.h in corgi-lcd (kernel test robot)
	* grammar fixes in commit messages
v2:
	* include backlight.h in fbtft (kernel test robot)
