firewire: ohci: obsolete OHCI_PARAM_DEBUG_BUSRESETS from debug module parameter

The OHCI_PARAM_DEBUG_BUSRESETS bit of debug module parameter was added at
a commit a007bb85 ("firewire: fw-ohci: conditionally log busReset
interrupts").

At the former commit, the bit becomes less meaningful, just to skip
logging.

This commit obsoletes it.
