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)
