Add a UCM configuration for the rt5650 codec. Tested on
a Samsung Chromebook 3. Adapted with minor modifications
from GitHub user evan-a-a's gist:

Interesting, thanks!

IIRC rt5650 is a low-cost version of rt5645, the machine driver only has 
a minor difference in the routing map and the controls are largely 
identical. Could we maybe factor the common codec parts with the include 
mechanism, similar to what was done for the SOC/platform driver settings?

I'll take a stab at parsing out the common configuration this weekend.
Seems like chtrt5645-mono-speaker-analog-mic can also be refactored to
use the shared code.

Any input on naming the shared directory? The existing shared
configurations all seem to be from the same codec. Maybe a
src/conf/ucm/codecs/rt5645-rt5650/ directory is in order.

IIRC there is also an alc3278 that's a low cost version of rt5645, so 
maybe rt5645-common is a more relevant name.
