o Rename ic_eoi to ic_clear to emphasize the functions it points

  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.
