serial: stm32: Fix unused-variable warning
If CONFIG_SERIAL_EARLYCON and CONFIG_OF are both not set,
gcc warns about unused variable:
drivers/tty/serial/stm32-usart.c:83:32: error: ‘stm32h7_info’ defined but not used [-Werror=unused-variable]
static struct stm32_usart_info stm32h7_info = {
^~~~~~~~~~~~
drivers/tty/serial/stm32-usart.c:61:32: error: ‘stm32f7_info’ defined but not used [-Werror=unused-variable]
static struct stm32_usart_info stm32f7_info = {
^~~~~~~~~~~~
drivers/tty/serial/stm32-usart.c:40:32: error: ‘stm32f4_info’ defined but not used [-Werror=unused-variable]
static struct stm32_usart_info stm32f4_info = {
^~~~~~~~~~~~
cc1: all warnings being treated as errors
Mark these variables as __maybe_unused to fix this.
