22d0785fde Implement apb_print_child().
Tested:

* AR9344, Atheros DB120 Reference board

e581852dd5 * Handle the three other timer interrupts for now, from the AR724x
later.  If the interrupts are ACKed even if they're not masked, we get
  the interrupts again later.  Grr.

* The AR724x and later chips want the interrupt bits cleared by writing the
  relevant bit to it, NOT by writing all but the current interrupt to it.

Tested:

* AR9344, DB120 reference board

TODO:

* Test ar724x and later chips to ensure no regressions have occured.

5543a1b98e Devices that rely on hints or identify routines for discovery need to
return BUS_PROBE_NOWILDCARD from their probe routines to avoid claiming
wildcard devices on their parent bus. Do a sweep through the MIPS tree.

50c5514227 Fix interrupt handling from the APB periperals (ie, UART) - it
also requires an explicit acknowledgement.

Tested:

* AR9344 (DB120) SoC

0580abc578 AR9330/AR9331 also needs to ACK the APB interrupt register, same as
AR724x.

This fixes 'stuck interrupt' problems I was having when writing the
uart interrupt code.

a5fbfee1d0 Move PMC hook invocation to cpu_intr. The idea is the same as with ast()
call but there is no reason to implement it in assembler.

fce0c7295d - Fix logic for detection if further processing of PMC should be performed.
pmc_intr returns one if one of the counters actually triggered the IRQ
- style(9) fixed

2a0fa68aca - Rename apb_intr to apb_filter since it's a filter handler
- Pass interrupt trapframe for handlers dow the chain
- Add PMC interrupt handler
    PMC interrupt is a special case, so we want handle it as soon as possible
    with minimum overhead. So we handle it apb filter routine.

4b7ec27007 - There's no need to overwrite the default device method with the default
one. Interestingly, these are actually the default for quite some time
  (bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
  since r52045) but even recently added device drivers do this unnecessarily.
  Discussed with: jhb, marcel
- While at it, use DEVMETHOD_END.
  Discussed with: jhb
- Also while at it, use __FBSDID.

9a70a84852 The AR724x SoC's require the irq status line to be acked/cleared.
This allows console IO to occur correctly once the kernel is in multi-user
mode.

3d844eddb7 bus_add_child: change type of order parameter to u_int
This reflects actual type used to store and compare child device orders.
Change is mostly done via a Coccinelle (soon to be devel/coccinelle)
semantic patch.
Verified by LINT+modules kernel builds.
