ALSA: hda - Set single_adc_amp flag for CS420x codecs



[ Upstream commit bad994f5b4ab57eec8d56c180edca00505c3eeb2 ]

CS420x codecs seem to deal only the single amps of ADC nodes even
though the nodes receive multiple inputs.  This leads to the
inconsistent amp value after S3/S4 resume, for example.

The fix is just to set codec->single_adc_amp flag.  Then the driver
handles these ADC amps as if single connections.
