[PATCH v2 1/5] gpio: of: Reflect decoupling of open collector and active low/high

[Charles Keepax <ckeepax@xxxxxxxxxxxxxxxxxxxxxxxxxxx>]

Commit 4c0facddb7d8 ("gpio: core: Decouple open drain/source flag with
active low/high") decoupled the open collector outputs from active
low/high but did not update the documentation.

Update the device tree documentation to correctly reflect this new
separation between the two concepts.

New to the series.

Thanks,
