Fix a compiler warning in serial_fdt.c
Even though the fserial_getc function is supposed to hang and never return if
it gets past its switch statement, gcc still throws a warning because that
path doesn't return anything. This change adds a return to pacify gcc.
BUG=chrome-os-partner:4993
TEST=Built and booted u-boot on an Alex.
