Pull media updates from Mauro Carvalho Chehab:
 - some V4L2 API updates needed by embedded devices
 - DVB API extensions for ATSC-MH delivery system, used in US for mobile
   TV
 - new tuners for fc0011/0012/0013 and tua9001
 - a new dvb driver for af9033/9035
 - a new ATSC-MH frontend (lg2160)
 - new remote controller keymaps
 - Removal of a few legacy webcam driver that got replaced by gspca on
   several kernel versions ago
 - a new driver for Exynos 4/5 webcams(s5pp fimc-lite)
 - a new webcam sensor driver (smiapp)
 - a new video input driver for embedded (sta2x1xx)
