[PATCH v7 0/6] hwmon: (dell-smm-hwmon) Convert to new hwmon registration api

[W_Armin@gmx.de]

From: Armin Wolf <W_Armin@gmx.de>

This patch series is converting the dell-smm-hwmon driver
to the new hwmon registration API. In order to do so,
it introduces a platform device in the first patch, and
applies some optimisations in the next three patches.
The switch to the new hwmon registration API is done in
the next patch. The last patch is fixing a small bug.

The caching of the fan/temp values was modified to better fit
the new hwmon API.

The patches work fine for my Dell Latitude C600, but i whould
appreciate someone testing the code on another model too.

Changes in v7:
- Add commit explaining why pwm1_enable has to be write-only

Changes in v6:
- Make pwm1_enable permissions write-only
- Do not test fan speed in dell_smm_is_visible()

Changes in v5:
- Fix checkpatch warning after patch 5/6
- Hide fanX_label if fan type calls are disallowed

Changes in v4:
- Make fan detection behave like before patch 5/6
- Update coverletter title

Changes in v3:
- Update description of patch 1/6 and remove empty change
- Let pwm1_enable remain write-only
- Include a small bugfix

Changes in v2:
- Fix coverletter title
- Update docs regarding pwm1_enable
