LCLS: make GCR into static member of osmo_lcls
Most of the time we'll have GCR filled anyway so it make sense to have it as static parameter instead of a pointer to separately allocated structure. Update tests to cover both static and dynamic osmo_lcls allocation variants. Change-Id: I905c36d8455911c68c30bc429379b7313dd46aea
