Add missing specification of efm32_uart_exit as module_exit.

This fixes the following compilation warning:

  drivers/tty/serial/efm32-uart.c:840:123: warning: ‘efm32_uart_exit’ defined but not used [-Wunused-function]

Hi,

This can be seen with e.g. arm allmodconfig.

Best regards,

V.

This warning doesn't occur in my builds, probably because I have
MODULES=n. I can reproduce it on allmodconfig though.
