CRAS: alsa_helpers: Fall back to max channels
Instead of giving up if none of the happy-list of channels is supported,
default to the max channel count of the card. This will allow cras to
function when new, high-channel-count devices are attached without
having to update the list manually.
For now this must be limited to 20 channels, until b/158509536 is fixed.
BUG=b:158506145
TEST=play to headphones of the TASCAM US-20x20.
