RZ/G2L GPT IP supports output pin disable function by dead time
error and detecting short-circuits between output pins.
Add documentation for the optional property renesas,poegs to
link a pair of GPT IOs with POEG.

v1->v2:
* removed quotes from ref
* Added maxItems and minItems for renesas,poegs property
* Added enums for gpt index
