[media] gspca: make arrays static, reduces object code size
Don't populate const arrays on the stack, instead make them
static. Makes the object code smaller by over 5200 bytes:
Before:
text data bss dec hex filename
58259 8880 128 67267 106c3 ov519.o
After:
text data bss dec hex filename
52155 9776 128 62059 f26b ov519.o
