Intel Alder Lake-P PCH reuses pinctrl IP from Tiger Lake-LP. Add user
friendly documentation for it.

Someone erroneously marked the bug as CLOSED INVALID, while only the
proposed resolution was INVALID and not the bug itself.

This patch solves the issue because it informs the user on the correct
driver to choose for Alder Lake-P.

Thanks for doing this!

Side note, though: this is not the only driver suffering of the similar issue.
Can you address them all?

We also have letter suffix for the above. Does this driver covers _all_ Tiger
Lake modifications?

If so, I would do

	  - Tiger Lake (all modifications)

> +	  - Alder Lake-P

I can tweak this when applying if confirmed, otherwise we would need
a revisit v2.

Yes, I was that person and I asked Raag to help with it.
Thanks, Raag!

Now we can close it again with PATCH_AVAILABLE.
