qcacld-3.0: Kbuild: Cleanup DP_OBJS logic

Currently DP_OBJS are added to OBJS when CONFIG_LITHIUM is enabled.
An upcoming change requires that assignments to OBJS be unconditional.
Fortunately most of the assignments to DP_OBJS are already protected
by this feature. Update the logic so that all of the assignments are
protected, and remove the condition from the OBJS assignment.
