[PATCH v2] dt-bindings: gpio: pca95xx: add onnn,pca9655 compatible

[Rosen Penev]

The pca9655 is the On Semi variant of the pca9555 16-bit I2C GPIO
expander. "onnn,pca9655" is already used standalone by in-tree DTS
(armada-388-clearfog, armada-388-helios4) and has a dedicated entry in
the pca953x driver's OF match table, but was never documented, causing
dtbs_check failures.

Document it alongside the other standalone entries such as
onnn,pca9654, without an nxp,pca9555 fallback, so that the existing
DTS remain valid.
