Add config options for stm32f4 boards 

This introduces the following configuration options to allow for easier
support for boards using the stm32f4 MCU

CLOCK_SPEED: This defines the clock speed in Hz
STM32_PLLM: This defines the PLLM parameter in the pll clock setup
STM32_PLLN: This defines the PLLN parameter in the pll clock setup
STM32_PLLP: This defines the PLLP parameter in the pll clock setup
STM32_PLLQ: This defines the PLLQ parameter in the pll clock setup
