xtensa: xtfpga: fix earlycon endianness
Serial port is attached to XTFPGA boards as native endian device, now that earlycon parameter parser understands mmio32native put it into earlycon kernel parameter. This makes early console functional on both little- and big-endian CPUs with identical kernel command lines. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
