[PATCH v2 0/3] Add initial devicetree for Turing RK1

Hi again list,

This is the second version of my patch to bring in support for the RK3588-based
Turing RK1 SoM. In my previous cover letter, I perhaps should have specified
that the RK1 is a little bit unusual in that, though it *is* a true SoM, it is
targeted toward home-hosting/edge users directly as a compute node, and as a
result the vast majority of users will be seeing it more like a
micro-bladeserver, rather than an off-the-shelf part meant to power a larger
system. This was my rationale for previously sending this as a single .dts,
targeting that use case.

However, Heiko previously made a good point that it still depends on a carrier
board to be "complete," and then I reminded myself that not all users will be
treating the RK1 like a mere "node" -- some will be incorporating them into
larger carriers, which the RK1 is meant to enable (not the other way around).

This version tries to strike a compromise, by moving the SoM-specific stuff to
a .dtsi, introducing a .dts specifically for the "opinionated" view of the RK1
as a carrier-agnostic node, and adding another paragraph to the PATCH 3/3
changelog explaining that.

I am wondering if there will be an objection about the .dts having the exact
same base filename and `compatible` as the .dtsi. I am not sure what word/term
to use to mean "RK1 but thought of as the system itself and not as a piece of a
system," but am open to suggestions. :)

Cheers all,
Sam
