From 95e12215caec0b4dba9a1d394e6cf7210ce6c30b Mon Sep 17 00:00:00 2001
From: Marti Bolivar <mbolivar@leaflabs.com>

Subject: Move nonportable bits of libmaple/stm32.h into libmaple/stm32f1.

These go in a new family header, libmaple/stm32f1/include/family/stm32.h.

While we're at it, do some reorganizing.
