[SERIAL] serial_cs: Use clean up multiport card detection
- Use ARRAY_SIZE() instead of home grown based version. - use parse->manfid.card rather than le16_to_cpu(buf[1]) - manfid.card is already converted to this format. - use info->prodid in subsequent tests rather than parse->manfid.card. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
