Subject: [PATCH 00/12] Adreno cooling, take 2

For the thermal framework to cool devfreq-managed devices properly,
it seems like the following conditions must be met:

1. the devfreq device has a cooling device associated with it
2. there exists some thermal zone provider
3. the cooling device is referenced in a cooling map
4. the cooling map is associated with a thermal trip point
5. the thermal trip point is of the "passive" kind
6. the "passive" trip point is being updated (via polling or otherwise)
7. the trip point is being hit (i.e. the thing gets hot enough)

Various QC DTs have various issues, mostly around 4, 5, 6 and 7.
This series tries to amend the platforms that currently can't have
Adreno throttled, without making much unnecessary/debatable mess,
although sneaking in some configuration unification/standardization.

Further updates can be made in the future.

This was originally brought into attention by Daniel in [1], this
series resolves the issues on a treewide scale.

Developed atop (and thereby depends on) [2].
