don't send and EOI which works like on amd64/i386 and blocks all
interrupts on the relevant interrupt controller.
o Replace the post_filter and post_inthread hooks registered when
creating the interrupt events with just ic_clear as on sparc64 we
don't need to do any disable->EOI->enable dance to unblock all but
the relevant interrupt while running the filter or handler; just
not clearing the interrupt already has the same effect.
o Merge from amd64/i386:
- Split the intr_table_lock into an sx lock used for most things,
and a spin lock to protect intrcnt_index.
- Add support for binding interrupts to CPUs, including for the
bus_bind_intr(9) interface, a assign_cpu hook and initially
shuffling interrupts arround in a round-robin fashion.
