tty/serial: add back missing setup_early_serial8250_console
Commit d2fd6810a823bcd (tty/serial: convert 8250 to generic earlycon) removed setup_early_serial8250_console, but there are still 2 callers in: arch/mips/mti-malta/malta-init.c drivers/firmware/pcdp.c Add back the function implemented as a wrapper to setup_earlycon.
