Configure STM32 system clock speed and flash size
Configures main system clock and flash size based on the target device. The console uart may be configured by using the `-DAVM_CFG_CONSOLE=` option, or for Nucleo devices the on board TTL->USB-COM can be configured with the `-DBOARD=nucleo` cmake option. Previously these values were hard coded in the C sources and needed to be changed manually if a device other than the default target was used. Closes #454 Signed-off-by: Winford <winford@object.stream>
