arch: arm: stm32l4: Add pin config for USART1 on PB6/PB7

Browse source 
With introduction of commit "pinmux: stm32: directly return error if
stm32_get_pin_config fails", pin configuration fails when
pins are not configured in pins[] array.
This was the case for configuration UART1 assigned on PB6/PB7.
