stm32f2: Improve GPIO alternate function support.
Add GPIO_AFRL and GPIO_AFRH bit definitions; these seem to have been overlooked. Add enum gpio_af to give labels to the various functions. Add gpio_set_af() convenience routine for configuring a GPIO's alternate function. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
