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.
