camera.$(TARGET_DEVICE): FPSRange gets defined twice for devices which
use the qcom camera hal and the QCOM_HARDWARE define. It is also defined
in frameworks/av/include/camera/CameraParameters.h . QCameraParameters.h
includes that header, so FPSRange should only be defined here if not
defined already.
