Previously, code which needed to work on all STM32F platforms needed
to specify them by name (CHIP_VARIANT_stm32f100 ||
CHIP_VARIANT_stm32f10x), and we needed extra symlinks in the
chip/stm32/ directory to allow the build system to find
family-specific files.
Add a CHIP_FAMILY level of abstraction, so that things which are
common across all STM32F platforms don't need to specify every STM32F
variant. Make the chip build look for family-specific filenames
instead of variant-specific filenames (except for config*.h, which is
actually variant specific).
In the few places where things actually are variant-specific, keep
using the existing CHIP_VARIANT defines.
Code refactoring only; no functional changes.

GPIO mapping is correct for current schematics.
Things to fix are #ifdef'd out with PORT_TO_PIT, but those require
changing other files (which is most tidily done in separate CLs).
