I'm not sure if this should be considered a bug or if it's an unimplemented/unnecessary feature.
When setting the frequency for the STM32F4 template it will only create a preprocessor symbol for HSE_VALUE but to get everything to work correctly one must set PLL_M, PLL_N, etc values in the system_stm32f4xx.c file.
So for me when using a 8MHz crystal I need to set PLL_N to 8 instead of the default 25.
