Documentation: gpio: Clarify effect of active low flag on line edges
The documentation does not make sufficiently clear that edge polarity is
based on changes to the logical line values, and that the physical
polarity of edges is dependent on the active low flag.
Clarify the relationship between the active low flag and edge polarity
for the functions that read edge events.
