The SPRD serial driver need to know which serial port would be used as console in an early period during initialization, the purpose is to keep the console port alive as possible even if there's some error caused by no clock configured under serial devicetree nodes. But with the patch [1], the console port couldn't be identified if missing console command line. So this patch adds using another interface to do check by reading stdout-path.
