V4L/DVB (3599a): Move drivers/usb/media to drivers/media/video
Because of historic reasons, there are two separate directories with V4L stuff. Most drivers are located at driver/media/video. However, some code for USB Webcams were inserted under drivers/usb/media. This makes difficult for module authors to know were things should be. Also, makes Kconfig menu confusing for normal users. This patch moves all V4L content under drivers/usb/media to drivers/media/video, and fixes Kconfig/Makefile entries.
