ALSA: ctxfi - Add subsystem option

Added a new option "subsystem" to override the PCI SSID for identifying
the card type.

reference_rate - reference sample rate, 44100 or 48000 (default)
multiple - multiple to ref. sample rate, 1 or 2 (default)
subsystem - override the PCI SSID for probing; the value
consists of SSVID << 16 | SSDID. The default is
zero, which means no override.
This module supports multiple cards.
