With recent improvements to serial/of core from Grant and Rob,
stdout-path alone suffices for setting up earlycon/console.

arc_uart driver is already equipped to handle that, switch the DT now.

ARC: [arcfpga] Early ARC UART to be only activated by cmdline 2014-06-03T08:50:09+00:00 Vineet Gupta vgupta@synopsys.com 2014-03-31T10:52:09+00:00 e87a850b9c92be6a8cf5735c516ec864d65f24dd Earlier CONFIG_SERIAL_ARC_CONSOLE would unconditionally enable the legacy ARC UART based early console even if platform lacked that UART (e.g. nSIM OSCI platform). So a multi-platform image containing the 2 UART drivers won't work. Fix that by probing the driver only if "earlyprintk=ttyARC0" is present in cmdline.
