[En-Nut-Discussion] STM32F1 USART1

[Achim]

Hi Uwe,

I think there´s a further mistake in the F1 USART: independent of the
selection of "Use alternate Pins" in qnutconf, the pins are always remapped
to port B. I realized this when debugging into Stm32UsartInit().
USART_TX and USART_RX have the values PB06 and PB07!
Unfortunately I´m not familiar enough with the configuration process to find
the mistake. But i think that somewhere "USART1_REMAP" (used in
stm32_usart_pinmux.h) is defined even if no remapping is selected.
