V4L/DVB (3399a): cpia2/cpia2_v4l.c cleanups

- make 2 needlessly global functions static

- remove cpia2_setup(): the driver already allows setting parameters
  through module_param(), and there's no reason for having two different
  ways for setting the same parameters

 	If the driver is compiled into the kernel, at boot time specify them
 like this:
-	cpia2=num_buffers:3,buffer_size:65535
+	cpia2.num_buffers=3 cpia2.buffer_size=65535
 
 	What buffer size should I use?
