firewire: ohci: cleanups and fix for nonstandard build without debug facility
1) Clean up two function names: The ohci_ prefix is only used in names
of fw_card_driver hooks. There were two unnecessary exceptions.
2) Replace empty macros by empty inline functions so that call parameter
type checking is available in #ifndef'd builds.
3) CONFIG_FIREWIRE_OHCI_DEBUG is currently a hidden kconfig variable,
hence is not going to be switched off by anybody. Still, it can be
switched off but then compilation will fail in ohci_enable() at the
expression param_debug & OHCI_PARAM_DEBUG_BUSRESETS. Add the necessary
definitions in the nonstandard case.
