This work improves Exynos thermal driver in various ways. This is
related to the discussion in
https://lore.kernel.org/all/97201878-3bb8-eac5-7fac-a690322ac43a@linaro.org/

The primary issue being fixed is a lockdep warning, which is fixed by
the thermal: exynos: use set_trips patch. We also simplify the code in
general.

Changelog:
v5:
- Used BIT wherever possible
- Simplified Exynos 7 code and used the correct register offsets for
Exynos 7
- Refactored some common register-setting code
v4:
- Resolved merge conflict when applying thermal: exynos: split
initialization of TMU and the thermal zone
- Reordered calls done when leaving exynos_tmu_initialize for
symmetry
v3:
- Fixed regulator initialization
- Fixed formatting of some comments
v2:
- Added missing field descriptions
- Removed an unnecessary field description
- Removed the commits that made clock management more fine-grained
(need more discussion), and adapted the new code to manage clocks
- Removed the devicetree changes (will be uploaded separately),
changing the recipient list accordingly
- Improved formatting of the devm_request_threaded_irq call
