Use stdout-path dts property for kernel console.

There were two socfpga boards left not using stdout-path:
socrates and vining. Make sure they match the other boards.

The reason is Dinh added that to all socfpga boards in his commit [1]
and I wanted the remaining two boards to be the same.

Isn't earlyprintk mostly a debugging aid ?
