Switch to explicitly using the Pro variant DT, which has been
available since Linux 4.11.

I separated out this change to the end of the series since it drew
questioning on prior review. I'd still advocate for making the change,
since especially with the additions of static variants and runtime
detection, it becomes easier from within a booted kernel to identify the
type and version of U-Boot image installed. Without making this change,
it becomes less direct to determine an actual Pro vs. Base, vs old
U-Boot image maybe supporting some hybrid variant configuration.
Even in the Linux kernel adding of the Pro DTS, it is indicated that it
was meant for backwards compatibility.
Except for cases where checking is done directly against the product
name from userspace, I don't see downsides even from a compatibility
perspective for not making this change. In cases where checking *is*
done from userspace, the broadening of the Clearfog product line would
seem to mean that userspace checking should be flagged as needing to be
udpated as well (or glob/regex matched as needed).
