qcacld-3.0: Converge on struct mobility_domain_info

The driver currently defines three different data structures to hold
mobility domain information:
- tSirMobilityDomainInfo
- tCsrMobilityDomainInfo
- struct mobility_domain_info

To align with the converged software architecture remove the two
legacy typedefs and exclusively use the unified WMI structure.
