serial: earlycon: Only try fdt when specify 'earlycon' exactly
When moving earlycon early_param handling to serial, the devicetree earlycons enable condition changed slightly. We used to only do that for 'console'/'earlycon', but now would also for 'console='/'earlycon='. Fix it by using the same condition like before. Fixes: d503187b6cc4 (of/serial: move earlycon early_param handling to serial) Signed-off-by: Jeffy Chen <jeffy.chen@rock-chips.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
