Documentation: move oneshot trigger attributes documentation to ABI
Documentation of sysfs interface should be in ABI in the first place. This moves relevant part of documentation and mentions where to look for it. Fix trivial typos whilst we are at it. Signed-off-by: Rafał Miłecki <rafal@milecki.pl> Signed-off-by: Jacek Anaszewski <j.anaszewski@samsung.com>

- LED_FULL brightness after it has been armed.
- Default to 100 ms.
-
- delay_off - specifies for how many milliseconds the LED has to stay at
- LED_OFF brightness after it has been armed.
