Draft: Practical Zephyr part 3 "Devicetree basics"

[lmapii]

Hi, this PR contains the third draft article for the article series about Zephyr. This one's about devicetree basics (semantics are part of the fourth article).

Next one is looking good! Left a lot of smaller comments, but overall another great addition. I definitely learned a decent amount with this entry.

The main point that I think might need some work is the best way to convey the types defined in the DTSpec and how they apply to Zephyr. I think my current thought is that it's easiest to connect the Format section 6.3 to the Zephyr implementation. I find the examples in this section are the easiest to map into Zephyr's types. The spec also is confusing with the prop-encoded-array term, I find it simplest to keep them as arrays of 32-bit integer cells. Any thoughts?

I had a hard time figuring out any conventions for Devicetree vs devicetree in the spec so I think the mixed use is fine

I did a quick pass and changed "devicetree" to "Devicetree, hope I got all of them! Now we're consistent with the Kconfig article.

@ejohnso49 thank you so much again for the review! I fixed the findings and applied the changes to the tables, hopefully they're a bit easier to understand now. I also removed most of the now dated <type> notations. You're completely right, there's no need for that and it's way over the top!

Excellent, I will give it another review later today. Thanks!
