mpt3sas: Define 'hba_mpi_version_belonged' IOC variable

Browse Source 
1. Use 'hba_mpi_version_belonged' IOC varable to uniquely identify each
individual generation driver functionality at runtime.

2. Declare global variable 'driver_name' and use this variable while
reserving PCI regions and while allocating the IRQs.
