Add TARGET_USES_HARDWARE_QCOM_GPS

Add TARGET_USES_HARDWARE_QCOM_GPS, which can be set to false
to disable using hardware/qcom/gps code.

Set this flag false for sdm845 and sdm710, which were using the
lack of chipset-specific directories for those projects as
an indirect mechanism not to compile code in this repo.
