Use devm helpers for regulator get and enable

NOTE: The series depends on commit
ee94aff2628b ("Devm helpers for regulator get and enable")
which currently sits in Mark's regulator/for-next

A few* drivers seem to pattern demonstrated by pseudocode:

- devm_regulator_get()
- regulator_enable()
- devm_add_action_or_reset(regulator_disable())

devm helpers for this pattern were added to remove bunch of code from
drivers. Typically following:

- replace 3 calls (devm_regulator_get[_optional](), regulator_enable(),
  devm_add_action_or_reset()) with just one
  (devm_regulator_get_enable[_optional]()).
- drop disable callback.

I believe this simplifies things by removing some dublicated code.

This series reowrks a few drivers. There is still plenty of fish in the
sea for people who like to improve the code (or count the beans ;]).

Finally - most of the converted drivers have not been tested (other than
compile-tested) due to lack of HW. All reviews and testing is _highly_
appreciated (as always!).

Revision history:

v3:
	- Drop already applied helper patches
	- Add a few more drivers

RFCv1 => v2:
	- Add devm_regulator_bulk_get_enable() and
	  devm_regulator_bulk_put()
	- Convert a couple of drivers to use the new
	  devm_regulator_bulk_get_enable().
	- Squash all IIO patches into one.

Patch 1:
	Add new devm-helper APIs to docs.
Patch 2:
	simplified CLK driver(s)
Patch 3:
	simplified GPU driver(s)
Patch 4 - 5:
	simplified hwmon driver(s)
Patch 6 - 14:
	simplified IIO driver(s)

hwmon uses a different pattern for the Subject line.

Thanks!

[01/14] docs: devres: regulator: Add new get_enable functions to devres.rst
        commit: 9048b9912f767ea9609e520678def446af804771

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
