Update the node name to be align with updated DT binding.  But be
noted that u-boot for ls1088a used the ifc node name to disable ifc-nor
node when the SoC is configured to use QSPI.  The u-boot has been
updated to use the latest name but the change could break
compatibility with older u-boot for ls1088a.
