First step towards fixing #301
The cubeprogdb has turned out to be a quite bad data source. It's not granular
enough (it has one entry per chip die, not per chip) so the previous code joined
the data with the C headers and cubedb to fill in the gaps, essentialy "guessing"
stuff. This has been quite error prone (see #301) and hard to make fixes to.
Instead, we're going to manually maintain memory maps in a .rs file. This way, if
something is wrong we can simply go and fix it.
This commit just migrates the existing data, even if it's wrong. (it does fix
a few very minor mistakes). Next steps is actually fixing the memory maps.
