Somewhat replaces some earlier work done by hg/lg, but much more
complete, so we kept it as is, because it's bringing in even more parts
after this.

Applies to both, and clearly shows that cmu.h needs to be extracted as
common code.
Originally from: e31d312331
and checked in the HG/LG reference manuals.
The original submitter of this squished everything into one series, and
has not returned. The code mostly appears good, and review comments were
followed for the most part. The project doesn't really maintain any
testing or board farm for sam3/sam4 parts, so we're going to just trust
our users.

fixed some typos from the manual and poor merging/rebaseing,
and one judgment call on using a specific name for a conflicting
bit definition.
stm32f0, l3, l4 are currently sharing the same duplicated header, and
stm32l0 uses the same peripheral. Stop copy-pasting stuff and centralize
definitions into a iwdg_common_v2.h header.
The stm32fx07 is common DesignWare IP, used in both STM32 and EFM32 chips.
Rename the files to make this more clear, and easier to use in other
targets.
This _breaks_ your gpio code for F2 and F4. It makes them consistent
with the reference manual, and more consistent with all other families
and general expectations.
