[media] drx-j: Remove duplicated firmware upload code
Remove the duplicated firmware upload code that was commented inside drxj.c. This code is not used, and will not work anyway, as it doesn't download the firmware from userspace. Acked-by: Devin Heitmueller <dheitmueller@kernellabs.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
