gsm23003: add osmo_mcc_from_str()
I found myself often using osmo_mnc_from_str() to also decode an MCC and be strict about it, but each time I felt the need to comment like "using osmo_mnc_from_str() also for MCC". Rather formalize this properly. Use a static inline function, no need to add more symbols to libosmo-gsm. Change-Id: I020a4f11791c61742a3d795f782805f7b7e8733e
