drm/nouveau/therm: move thermal-related functions to the therm subdev
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
