[media] saa7134: use input types, instead of hardcoding strings
Currently, the saa7134 driver is hardcoding input names on each board entry. More modern drivers define, instead, an enum for each input type. While the current logic works, it adds extra complexity at the driver, as it needs to discover the type of the input using some euristics. Instead, let's standardize the input types and use a type, instead of a name on all places. That will allow further patches to properly report the input type via VIDIOC_G_INPUT and to remove an extra field from the struct to identify if the input is for TV. Please notice that several boards define an input for receiving composite signals via a S-Video connector. The name of such input was inconsistent, so this patch cleans it and make it to be properly reported the same way for all boards. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
