returns -ERANGE.

Ilia Mirkin 7a22c737fa drm/nouveau: fix temp/pwm visibility, skip hwmon when no sensors exist
A NV34 GPU was seeing temp and pwm entries in hwmon, which would error
out when read. These should not have been visible, but also the whole
hwmon object should just not have been registered in the first place.

Oscar Salvador b28d78f187 drm/nouveau/hwmon: expose the auto_point and pwm_min/max attrs
This patch creates a special group attributes for attrs like "*auto_point*".
We check if we have support for them, and if we do, we gather them all in
an attribute_group's structure which is the parameter regarding special groups
of hwmon_device_register_with_info
We also do the same for pwm_min/max attrs.

Oscar Salvador bfb96e4c34 drm/nouveau/hwmon: Remove old code, add .write/.read operations
This patch removes old code related to the old api and transforms the
functions for the new api. It also adds the .write and .read operations.

Oscar Salvador dbddaaf083 drm/nouveau/hwmon: Add nouveau_hwmon_ops structure with .is_visible/.read_string
This patch introduces the nouveau_hwmon_ops structure, sets up
.is_visible and .read_string operations and adds all the functions
for these operations.
This is also a preparation for the next patches, where most of the
work is being done.
This code doesn't interacture with the old one.
It's just to make easier the review of all patches.

Alexandre Courbot f2014cd02c drm/nouveau/hwmon: fix crash on non-PCI platforms
Registration of the hwmon device will fail on non-PCI systems since
dev->pdev is NULL in that case. Use the more generic drm_device::dev
member that points to the same and is always set no matter the platform.

Ben Skeggs be83cd4ef9 drm/nouveau: finalise nvkm namespace switch (no binary change)
The namespace of NVKM is being changed to nvkm_ instead of nouveau_,
which will be used for the DRM part of the driver.  This is being
done in order to make it very clear as to what part of the driver a
given symbol belongs to, and as a minor step towards splitting the
DRM driver out to be able to stand on its own (for virt).

Because there's already a large amount of churn here anyway, this is
as good a time as any to also switch to NVIDIA's device and chipset
naming to ease collaboration with them.

A comparison of objdump disassemblies proves no code changes.

NVKM is having it's namespace switched to nvkm_, which will conflict
with these functions (which are workarounds for the fact that as of
yet, we still aren't able to split DRM and NVKM completely).
