[TOPIC-GPIO] revisions to 802154 driver PR

[pabigot]

This PR augments #22241 with additional commits to resolve various problems.

From #22241 (comment) are fixes to the devicetree binding names, along with other build errors.

Also added are platform configurations to test the driver builds. For CC1200 the resulting application does not link due to configuration conflicts.

All checks are passing now.

NOTE: For some of the reported defects, checkpatch may be able to
      mechanically convert to the typical style using --fix or --fix-inplace.

Your patch has style problems, please review.

@jfischer-phytec-iot This is essentially the same as the branch you provided (thanks) except that I added a copyright statement for the sample overlay to avoid a checkpatch warning.

I also added a commit to address @mnkp's request for consistent GPIO initial output values.

[mnkp]

Let's initialize all outputs to a known value.

[pabigot]

Low seems to be the off/in-reset state so I went with that.
