Move Flash support for STM32F1 to libmaple/stm32f1/.
This is a backwards-compatible change.
The Flash registers on the STM32F2 line are different than on
STM32F1. Therefore, move the register map and bit definitions to new
libmaple/stm32f1/include/family/flash.h.
Move flash_enable_prefetch() from libmaple/flash.c to new
libmaple/stm32f1/flash.c. The remaining pieces of libmaple/flash.c use
a common subset of the Flash registers, so they're's portable to F2,
and that's all we're currently interested in.
