[PATCH v4 01/12] DT: leds: Improve description of flash LEDs related properties

[Jacek Anaszewski <j.anaszewski@samsung.com>]

Description of flash LEDs related properties was not precise regarding
the state of corresponding settings in case a property is missing.
Add relevant statements.
Removed is also the requirement making the flash-max-microamp
property obligatory for flash LEDs. It was inconsistent as the property
is defined as optional. Devices which require the property will have
to assert this in their DT bindings.
