While some SMI LARBs are linked to SMI sub common, then SMI sub common is linked to SMI common. Add 'mediatek,smi-sub-comm' and 'mediatek,smi-sub-comm-in-portid' properties here. The SMI reset driver could query which port of the SMI sub common the current LARB is linked to through the two properties. The hardware block diagram could be described as below.
