powerpc/legacy_serial: Warn about 8250 devices operated without active FSL workarounds
If the 8250 driver is built as a module (or built-in without console
support) the Freescale specific workaround were silently not activated.
Add a warning in this case.
Currently CONFIG_SERIAL_8250_FSL=y implies that the function
fsl8250_handle_irq() is built-in and can be used. However with the
changes of the next commit CONFIG_SERIAL_8250_FSL might be enabled also
when the 8250 driver is a module and so more care is needed when
fsl8250_handle_irq() is to be used. The code added here is able to
handle the new situation already.
