drivers/tty/serial: Remove unused function early_mcf_setup

Compiling a kernel for the ColdFire causes a compiler warning:

drivers/tty/serial/mcf.c:473:12: warning: no previous prototype for
 ‘early_mcf_setup’ [-Wmissing-prototypes]
  473 | int __init early_mcf_setup(struct mcf_platform_uart *platp)
      |            ^~~~~~~~~~~~~~~

This function seems to be completely unused, so let's remove it
to silence the warning.
