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.

This adds the following sysfs attributes to the LED:



  delay_on - specifies for how many milliseconds the LED has to stay at

             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.

              Default to 100 ms.



  invert - reverse the blink logic.  If set to 0 (default) blink on for delay_on

           ms, then blink off for delay_off ms, leaving the LED normally off.  If

           set to 1, blink off for delay_off ms, then blink on for delay_on ms,

           leaving the LED normally on.

           Setting this value also immediately change the LED state.



  shot - write any non-empty string to signal an events, this starts a blink

         sequence if not already running.

This adds sysfs attributes to the LED that are documented in:
