Drop "Optional regulator for"

Also, vdd is mandatory, not optional. How device can work without supply?

Drop "Optional GPIO specifier for the". Don't repeat constraints in free
form text. Schema tells what is optional or what is not. This also
cannot be anything else than GPIO specifier, so repeating obvious is not
making it more readable.

Drop "Optional GPIO specifier for the".

Drop description completely. Redundant. It cannot be anything else than
reset pin.
