Subject: hardware: Fix up board pages.

Make the following changes to each of the board files under
source/hardware/:

- Link to ST docs from MCU name in Technical Specifications.
- Tweak RM0008 description.
- Beautify technical specifications.
- Note that pin maps aren't exhaustive.

It's becoming clear that we should eventually use some kind of
templating language to get these pages done, but it's still overkill
for now.
