PowerBooks.

Add a sysctl to allow disabling the monitoring thread.

Summary:
If a user uses powerd, or doesn't want to use the cycles monitoring, they can
now suspend the monitoring thread.

While here, reorganize the added prototypes to match existing groupings.

Add an AC line monitor so power_profile can work

Summary:
Add a polling loop (1Hz) to monitor the battery and AC status, to notify devd
like ACPI does for power monitoring. This allows /etc/rc.d/power_profile to
work on PowerPC laptops

Test Plan:
Tested on a Titanium PowerBook, configuring economy_cpu_freq and
performance_cpu_freq, disabling powerd.

- 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.

Restructure how reset and poweroff are handled on PowerPC systems, since
the existing code was very platform specific, and broken for SMP systems
trying to reboot from KDB.

- Add a new PLATFORM_RESET() method to the platform KOBJ interface, and
migrate existing reset functions into platform modules.
- Modify the OF_reboot() routine to submit the request by hand to avoid
the IPIs involved in the regular openfirmware() routine. This fixes
reboot from KDB on SMP machines.
- Move non-KDB reset and poweroff functions on the Powermac platform
into the relevant power control drivers (cuda, pmu, smu), instead of
using them through the Open Firmware backdoor.
- Rename platform_chrp to platform_powermac since it has become
increasingly Powermac specific. When we gain support for IBM systems,
we will grow a new platform_chrp.

Remove the unneeded header <machine/intr.h>.

Get nexus(4) out of the RTC business. The interface used by nexus(4)
in Open Firmware was Apple-specific, and we have complete coverage of Apple
system controllers, so move RTC responsibilities into the system controller
drivers. This avoids interesting problems from manipulating these devices
through Open Firmware behind the backs of their drivers.

Provide an analogous sysctl to hw.acpi.acline (dev.pmu.0.acline) to
determine whether the computer is plugged in to mains power.

Add the ability to control the sleep LED with led(4). Adding this fairly
useless feature gives us a reasonably complete PMU implementation.

Add facilities to pmu(4) to interrogate battery status on Apple PowerPC
laptops. This includes battery presence detection, charging status, current
and voltage readouts, and charge level indication. The sysctl interface
is somewhat ACPI-like.

Add support for automated reboot after power failure on Apple Core99 machines
(G3 laptops, all G4 machines, early G5s, G5 Xserves). The relevant sysctl
is named dev.pmu.0.server_mode for mental compatibility with Linux.

Fix some possible infinite loops in the ADB code, and remove some hacks
that were inserted in desperation during bring-up. In addition, move ADB bus
enumeration and child attachment to when interrupts are available.

Add ADB support. This provides support for the external ADB bus on the PowerMac
G3 as well as the internal ADB keyboard and mice in PowerBooks and iBooks. This
also brings in Mac GPIO support, for which we should eventually have a better
interface.
