Actually commit 6d49b3a0f351 ("gpio: pca953x: Add support for the On Semi
pca9655") added this compatible to the driver back in 2021 but it had remained
undocumented until now. Unfortunately there's no denying I signed off on it. :(

This commit should probably contain a Fixes: tag pointing at this commit.
