This patch add earlycon support to MT8173 SoC platform.
To use earlycon, need
1. Add earlycon in boot parameters
2. Add "linux,sdtout-path" property in device tree file

This patch based on 4.1-rc1.

Change in v3:
Remove noinit options, not necessary, because 8250_early.c will not init hardware
if not provide baudrate.

Change v2:
1. Add noinit options.
2. Remove duplicate code in 8250_mtk.c, reuse the 8250_early.c existed function.

Eddie Huang (3):
  tty: serial: 8250: export early_serial8250_setup function
  tty: serial: 8250_mtk: Add earlycon
  arm64: dts: Add mediatek MT8173 earlycon support
