Device fixups (nw)
- c2040fdc, c64h156: Calculate clock period in device_clock_changed rather than in constructor - isa8, isa16: Eliminate device_config_complete (probably unnecessary, since m_maincpu is already set in device_start) These changes prevent assert failures with the new ad-hoc device construction in -listxml, though they are otherwise independent.
