mainboard/google/poppy: Add clock frequency for camera sensors
Add clock frequency property into _DSD ACPI object and set it to 19.2MHz for camera sensors. Upstream camera kernel has added a check for clock frequency in sensor probe function and without this property sensor probe fails. BUG=b:38326541 BRANCH=none TEST=Build and boot poppy. Dump and verify that the generated DSDT table has the required entries. Verified that sensor probe is successfull.
