Felix Held e84c3f1898 soc/amd/*/mca: factor out common MCA/MCAX check & print functionality
For Cezanne stubs are added for the functions that the SoC-specific code
needs to provide. Since the mca_is_valid_bank stub on Cezanne always
returns false, the checks get skipped for it at the moment. The actual
functionality will be added in a later patch.
