a175094cd8 drm/nouveau/pm: introduce generic handler for on-chip fan controller
The handling of the internal pwm fan controller is similar enough between
current chipsets that it makes sense to share the logic, and bugfixes :)

No hw backends converted yet, will automatically fall-through to the
"old" per-chipset fanspeed hooks for now.

11b7d89521 drm/nouveau/pm: manual pwm fanspeed management for nv40+ boards
Exposes the following sysfs entries:
- fan0_input: read the rotational speed of the fan (poll a bit during 250ms)
- pwm0: set the pwm duty cycle
- pwm0_min/max: set the minimum/maximum pwm value

v2 (Ben Skeggs):
- nv50 pwm controller code removed in favour of other more complete code
- FAN_RPM -> FAN_SENSE
- merged FAN_SENSE readout into common code, not at all nv50-specific
- protected fanspeed changes with perflvl_wr
- formatting tidying
- added some comments where things are shaky

v3 (Martin Peres)
- ensure duty min/max from thermal table are sane

658e86ee2d drm/nouveau: enable hwmon support when both nouveau/hwmon are built as modules.
The nouveau hwmon temperature support currently only functions when hwmon is
compiled into the kernel. There's no reason why this shouldn't also work when
both hwmon and nouveau are modularised (as is the case with Slackware's stock
kernels).

5c6dc65754 drm/nouveau: pass perflvl struct to clock_pre()

be modified with the memclk.  Just pass in the entire perflvl struct and
let the chipset-specific code decide what to do.

7760fcb020 drm/nouveau: Import initial memory timing work
This isn't correct everywhere yet, but since we don't use the data yet
it's perfectly safe to push in, and the information we gain from logs
will help to fix the remaining issues.

v2 (Ben Skeggs <bskeggs@redhat.com>):
- fixed up formatting
- free parsed timing info on takedown
- switched timing table printout to debug loglevel

0fbb114af7 drm/nouveau: Parse old style perf tables.
Used on nv17-nv28, they contain memory clocks and timings, only one of
the table entries can actually be used, depending on the RAMCFG
straps, and it's usually higher than the frequency programmed on boot
by the BIOS.

The memory timings listed in table version 0x1x are used to init the
0x12xx range but they aren't required for reclocking to work.
