[PATCH] python: Add a top-level requirements.txt file

[Tom Rini]

A frequently reported problem is that someone misses a required python
package when doing a specific task within U-Boot. This is in turn
because each of our requirements.txt files only lists their direct
dependencies. It is not always clear that another tool has its own
requirements and thus something else fails. Solve this by having a top
level requirements.txt file for the project which in turn installs all
of our other project requirements.txt files.

As Kory is the most recent person to hit this, cc'ing them. I think this
is the right path forward and if agreed, I'll update documentation in a
follow-up.
