[ALSA] [PPC,SOUND] Fix audio gpio state detection
When booting with line out or headphone plugged, you won't hear anything.
The problem is that after reset all channels are muted, but the actual
value of the gpio port doesn't exactly match the active_val settings as
expected by check_audio_gpio. For example, the line_mute port is set to
7, but check_audio_gpio would expect 0xd or 0xf, thus its return value
indicates that it is not active, even though it is. AFAICS only looking
at the low bit is enough to determine whether the port is active.
