Most OMAP FB LCD drivers don't have anything to do in their panel
callbacks. This leads to a large set of empty boilerplate functions in the
panel drivers. Make those callbacks optional by checking if they are set
before calling them. This allows those boilerplate functions to be removed.

None of the lcd_panel structs defined by the OMAP LCD drivers are
referenced outside of their compilation unit. Follow best practices and
mark them as static.

Every single one of the OMAP fbdev LCD drivers implements no-op remove,
suspend and resume callbacks for their platform_driver. This is not
necessary as the driver core handles the case where the callbacks are not
set just fine. So they are just unnecessary boilerplate that can be
removed.

Most arches have an asm/gpio.h that merely includes linux/gpio.h. The
others select ARCH_HAVE_CUSTOM_GPIO_H, and when that's selected,
linux/gpio.h includes asm/gpio.h.
Therefore, code should include linux/gpio.h instead of including asm/gpio.h
directly.
Remove includes of asm/gpio.h, adding an include of linux/gpio.h when
necessary.
This is a follow-on to 7563bbf89d ("gpiolib/arches: Centralise
bolierplate asm/gpio.h").

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.
