[opensuse-arm] iMX51 - Update config for 3.4-rc2 + enable Multimedia support

Please find in attachment a patch for the iMX51 config. I took the config from kernel-source/config/armv7l/imx51 and I added Multimedia support via menuconfig. It compiles (uImage + modules) but I haven't tested it since I have no iMX51 board. Regards, Guillaume
