Fixed terminal UART GPIO initialization. Even though UART was working, the previous UART TX (P5.0) initialization was making CAN TX (P3.2) not work, apparently because of IPConnected_Enabled on the GPIO_InitStructure. Probably it is safer always refresh the GPIO_InitStructure for every pin configuration on STR912.
