Subject: [PATCH 1/6] serial: export fsl8250_handle_irq

fsl8250_handle_irq is now used by the of_serial driver, and that fails
if it is a loadable module:

ERROR: "fsl8250_handle_irq" [drivers/tty/serial/of_serial.ko] undefined!

This exports the symbol to avoid randconfig errors.

Signed-off-by: Arnd Bergmann <arnd@...db.de>
Fixes: d43b54d269d2 ("serial: Enable Freescale 16550 workaround on arm")
