platform/x86: int3472: Export int3472_discrete_parse_crs()

Browse Source 
At the moment the atomisp has duplicate code for parsing Intel camera
sensor GPIOS and calling the special 79234640-9e10-4fea-a5c1-b5aa8b19756f
_DSM to get the GPIO type and map it to the sensor.

Export int3472_discrete_parse_crs() so that the atomisp driver can reuse
the INT3472 code for this.
