V4L/DVB (5515): Use a better format to represent usbvision supported boards

Changed usbvision cards table to allow:
	1) Not repeat USB ID on two structs;
	2) Not need to specify both usb and card description tables at
	   the same order, removing some magic;
Some cards had duplicated names. Fixed.
A test for an specific board were doing by using a string comparation.
The comparation were wrong. Also, it is not a good practice to recognize
a board based on his string name.
