Add support for new smu-firmware fan commands. This fixes wrong sysctl
hw.sensors fan values seen on macppc models with a new smu-firmware.

Help and ok kettenis

Hook up smu(4) to the thermal management framework.

ok kettenis

Move rpm read to a own function analog pwm read. No functional change.

Add support for pwm fans.

ok kettenis

Return correct rpm values for all fans.

Fall back to "safe-value" when "unmanage-value" is not evailable to
configure fan speeds.

The (no quite so) new kernel perfpolicy code calls cpu_setperf() from a
timeout. Unfortunately the smu(4) CPU voltage slewing code sleeps, which
causes a kernel panic. Prevent this by delegating the CPU frequency switching
and voltage slewing to a task.

Bump the fan limit and avoid a panic on my quad G5.

Unify various gpio access using methods that take an offset relative to the
mac-io bus base address. Needed by upcoming dfs(4) support.

On some Apple machines, the openfirmware returns a gpio offset relative to
the gpio controller (generaly at 0x50). These offsets should be corrected
to be relative to the bus base address.

Apple is hopelessly inconsistent with their firmware, so some machines have
an extra smu-i2c-control node where others don't. Handle the difference.
Makes the PowerMac9,1 actually find some i2c devices.

Add support for the "Slots Power" sensor on the PowerMac9,1.

The PowerMac9,1 has 4 sensors on its smu(4), so increase the maximum number.
Also add a check for the maximum number of sensors like we already have for
the number of fans such that we avoid mysterious hangs on machines with
more than 4 sensors.

Make SMU sensors and fan control work on PowerMac8,1.

tested by Alastair Poole.

On the first generation iMac G5 (PowerMac8,1) the fans node is called
rpm-fans.

Don't attach sensors and iic(4) if we didn't find any fans.
Tickling the SMU when we don't set the fans running is bad since this
prevents the fans to spin up automatically causing the machine to overheat.

Add support for cpu voltage slewing.

Remove unnecessary lockmgr() archaism that was costing too much in terms
of panics and bugfixes. Access curproc directly, do not expect a process
pointer as an argument. Should fix many "process context required" bugs.
