The symlinks were annoying some people, and they're not used anywhere
else in the kernel tree. The include directory structure has been
changed so that symlinks aren't needed anymore.
NVKM has been moved from core/ to nvkm/ to make it more obvious as to
what the directory is for, and as some minor prep for when NVKM gets
split out into its own module (virt) at a later date.

Therm uses 3 ptimer alarms. Two to drive the fan and one for polling the
temperature. When suspending/resuming, alarms will never be fired.
As we are checking if there isn't an alarm pending before rescheduling
another one, we end up never checking temperature or updating the
fan speed.
This commit also adds debug messages to be able to spot more easily
if this case happens again in the future. Sorry for the spam if you
activate the debug level though.

The kernel message "[ PTHERM][0000:01:00.0] Thermal management: disabled"
is misleading as it actually means "fan management: disabled".
This patch fixes both the source and the message to improve readability.

In nouveau_therm_sensor_event, temperature is stored as an uint8_t
even though the original interface returns an int.
This change should make it more obvious when the sensor is either
very-ill-calibrated or when we selected the wrong sensor style
on the nv40 family.

+ the same for shutdown threshold - seems impossible, but shutdown can fail.

This should avoid the situation where a user gets its kernel logs flooded when
temperature oscillates around a threshold with 0°C hysteresis.
This patch is just meant to fix broken vbios (as reported on a nv4e on
sysfs hwmon interface.

For now, we only boost the fan speed to the maximum and auto-mode
when hitting the FAN_BOOST threshold and halt the computer when it
reaches the shutdown temperature. The downclock and critical thresholds
do nothing.
On nv43:50 and nva3+, temperature is polled because of the limited hardware.
I'll improve the nva3+ situation by implementing alarm management in PDAEMON
whenever I can but polling once every second shouldn't be such a problem.
v2 (Ben Skeggs):
- rebased

It looks scary because of the size, but I tried to keep the differences minimal.
Further patches will fix the actual "driver" code and add new features.
v2: change filenames, split to submodules
v3: add a missing include
v4: Ben Skeggs <bskeggs@redhat.com>
- fixed set_defaults() to allow min_duty < 30 (thermal table will
override this if it's actually necessary)
- fixed set_defaults() to not provide pwm_freq so nv4x (which only has
pwm_div) can actually work. the boards using pwm_freq will have a
thermal table entry to provide us the value.
- removed unused files
