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.
