Takashi Sakamoto 6921b16099 ALSA: bebob: fix to detect configured source of sampling clock for Focusrite Saffire Pro i/o series 
commit 706ad6746a upstream.

For Focusrite Saffire Pro i/o, the lowest 8 bits of register represents
configured source of sampling clock. The next lowest 8 bits represents
whether the configured source is actually detected or not just after
the register is changed for the source.

Current implementation evaluates whole the register to detect configured
source. This results in failure due to the next lowest 8 bits when the
source is connected in advance.

This commit fixes the bug.
