Some fixes to the current RMI interrupt handling, changes in this patch are:

- (cleanup) remove rmi specific 'struct mips_intrhand' - this is no
longer needed since 'struct intr_event' have all the required hooks
- add xlr_cpu_establish_hardintr, which has args for pre/post ithread
and filter hooks, so that the PCI code can add the PCI controller
interrupt ack code here
- make 'cpu_establish_hardintr' use the above function.
- (fix) change type of eirr/eimr from register_t to uint64_t. These
have to be 64bit otherwise we cannot handle interrupts from 32.
- (fix) use eimr to mask eirr before checking interrupts, so that we
will not handle masked interrupts.
