ALSA: bebob: Fix failure to detect source of clock for Terratec Phase 88
commit 3f4032861cfbff0b9134bf94c5c92e2146d1f068 upstream. This patch fixes a failure to open PCM device with -ENOSYS in Terratec Phase 88. Terratec Phase 88 has two Selector Function Blocks of AVC Audio subunit to switch source of clock. One is to switch internal/external for the source and another is to switch word/spdif for the external clock. The IDs for these Selector Function Blocks are 9 and 8. But in current implementation they're 0 and 0.
