Document the commonly used LED triggers by the SoCs. Not all triggers
are documented as some of them are very application specific. Most of the
triggers documented here are currently used in devicetrees of many SoCs.

While at it, also place the comment above the triggers (hci, mmc, wlan)
to match the rest of the binding.

Changes in v6:

* Rebased on top of lee/for-leds-next branch
* Fixed the comment location for few triggers

Changes in v5:

* Rebased on top of v6.2-rc1

Changes in v4:

* Removed the sorting of triggers
* Removed the "items" as they were not needed
* Reworded the description
* Dropped Zhen Lei's tested-by tag as the patch has changed
* Added kbd-capslock trigger

Changes in v3:

* Rebased on top of v6.1-rc1
* Added WLAN Rx trigger
* Added tested tag from Zhen Lei

Changes in v2:

* Added more triggers, fixed the regex
* Sorted triggers in ascending order
