arch/arm/stm32h7: Handle serial lookup without UARTs.
Compile stm32_serial_get_uart() only when HAVE_UART is defined,
matching the condition that guards its g_uart_devs device table.
Without this guard, enabling serial support with all hardware UARTs
disabled fails to compile because the table is not defined.
Follow the conditional function definition used by the common STM32
serial driver. Keep the UART lookup function body unchanged.
Validation:
- Reproduced the undeclared g_uart_devs error on unmodified upstream.
- Built nucleo-h743zi:nsh with USART3 enabled and with all hardware
UARTs disabled and the USB CDC ACM console enabled.
- Confirmed the lookup symbol is present only in the UART-enabled
object and the function body is identical to upstream.
- Patch style and whitespace checks passed.
