This PR removes kokkos specific code from spiner for the getondevice function. Addresses #54

@mauneyc-LANL @Yurlungur please take a look. I think poc needs more functionality to expose information about memory/execution spaces so that I don't need the hacky preprocessor stuff.

I should also note that this won't work until the latest changes from ports-of-call are pulled in.
