Overvoltage protection and brightness mode are currently hardcoded
as 29V and disabled in the driver. Make these configurable via DT.

Besides addressing review comments v3 folds in the patches to
disable the chip and turn of the regulator on brightness 0 from

Besides addressing review comments v2 also allows to limit the maximum led
current.

Patches are against next-20191220.

Changes from v2
- As per review comment from Pavel Machek
  https://lore.kernel.org/linux-leds/20191226100615.GA4033@amd/T/#u
  - Use default value in DT example
  https://lore.kernel.org/linux-leds/20191226100842.GC4033@amd/T/#u
  - Use uppercase LED in commit message
  https://lore.kernel.org/linux-leds/20191226101336.GD4033@amd/T/#u
  - Fix typo in commit message
  - Use correct return value when checking if property is present
  - Fold in
    https://lore.kernel.org/linux-leds/20191226101419.GE4033@amd/T/#t
- Add Acked-By's from Pavel Machek, thanks!

Changes from v1
- As per review comments by Dan Murphy
  https://lore.kernel.org/linux-leds/3d66b07d-b4c5-43e6-4378-d63cc84b8d43@ti.com/
  - Split commits per propoerty
  - Add new properties to DT example too
  - Drop dev_dbg() statements
  - ovp: fix 21V value parsing
  - ovp: Set correct default value if DT parsing fails
- As per review comments by Pavel Machek
  https://lore.kernel.org/linux-leds/20191221191515.GF32732@amd/
  - Fix defaults (which is 29V)
  - Use uV as Unit for ovp property
- Change property name to 'ti,ovp-microvolt' to make it shorter
- Honor led-max-microamp to not exceed the maximum led current
