[v3] dt-bindings: gpio: pca953x: Add support for the NXP PCAL9554B/C

The NXP PCAL9554B is a variant of the PCA953x GPIO expander,
with 8 GPIOs, latched interrupts and some advanced configuration
options. The "C" version only differs in I2C address.

This adds the entry to the devicetree bindings.

Please add Acked-by/Reviewed-by tags when posting new versions. However,
there's no need to repost patches *only* to add the tags. The upstream
maintainer will do that for acks received on the version they apply.

If a tag was not added on purpose, please state why and what changed.

Hi Mike,

please resend this rebased on top of v5.10-rc1 with tags collected if
you still want it merged.

This triggers my OCD. Putting B before A? Please make it alphabetic.

No big deal, but...

Nothing wrong with a bit of OCD, it's probably in our job description :)

But there's a "4" before the "5" too.

My perception isn't as good as my OCD apparently :D

This is already merged anyways, no big deal.
