ALSA: fireface: fix reference to wrong register for clock configuration

Browse source 
commit fa9c98e4b975bb3192ed6af09d9fa282ed3cd8a0 upstream.

In an initial commit, 'SYNC_STATUS' register is referred to get
clock configuration, however this is wrong, according to my local
note at hand for reverse-engineering about packet dump. It should
be 'CLOCK_CONFIG' register. Actually, ff400_dump_clock_config()
is correctly programmed.

This commit fixes the bug.
