V4L/DVB (3405): Fixes tvp5150a/am1 detection.
- Tvp5150 type were determined by a secondary register instead of using ROM code. - tvp5150am1 have ROM=4.0, while tvp5150a have ROM=3.33 (decimal). All other ROM versions are reported as unknown tvp5150. - Except for reporting, current code doesn't enable any special feature for tvp5150am1 or tvp5150a. Code should work for both models (but were tested only for tvp5150am1). Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
