serial/arc-uart: platform_data order changed
* is_emulated is now 1st element, rather than last * also tucked all platform data refs together Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Cc: Alan Cox <alan@linux.intel.com> Cc: Jiri Slaby <jslaby@suse.cz> Cc: linux-serial@vger.kernel.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
