[PATCH] serial: 8250_mid: Add missing module namespace import for SERIAL_8250

[Nathan Chancellor]

After commit 1c305d5f1daa ("serial: 8250_mid: wait for LSR tx empty
before setting termios"), modpost errors (or warning with
CONFIG_MODULE_ALLOW_MISSING_NAMESPACE_IMPORTS=y):

  ERROR: modpost: drivers/tty/serial/8250/8250_mid.ko: module uses symbol 'serial8250_wait_for_xmitr' from namespace 'SERIAL_8250', but does not import it.

Add the missing module namespace import to clear up the error/warning.

Fixes: 1c305d5f1daa ("serial: 8250_mid: wait for LSR tx empty before setting termios")
