[PATCH] m68k: completely initialize hw_regs_t in ide_setup_ports

ide_setup_ports does not completely initialize the hw_regs_t structure which
can cause random failures, as the structure is often on the stack.  None of
the callers expect a partially initialized structure, i.e.  none of them do
any setup of their own before calling ide_setup_ports().
