Merge patch series "introduce basic support for TI's am625-lp-sk"

Bryan Brattlof <bb@ti.com> says:

Hello Again Everyone!

The am625-lp-sk is a variant of the am625-sk showcasing the low-power
features of the am625 SoC Family. Because it's essentially a board and
package spin of the am625-sk I've inherited the am625 configuration and
overridden what was needed.

This is a new spin of Nitin's original work which has been updated
significantly since October 2023

For those of us interested here is proof of life using buildroot:

   https://paste.sr.ht/~bryanb/40f7787f7760bee383aa8fbc342a29e8544dbdab

This also works around a buildman issue not following #include
directives. To get around this I've redefined the variables it's looking
for inside the lp-sk defconfig to keep it happy for now. I made a pull
request on github and everything seems like it's happy
