[media] ati_remote: Add comments to keycode table
A more detailed description of what the buttons look like and their intended function makes it easier for people to maintain this code without access to the hardware. [m.chehab@samsung.com: Fixed a typo "Mdeia" instead of "Media"] Signed-off-by: George Spelvin <linux@horizon.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
