arm64: dts: qcom: sc7280: align TLMM pin configuration with DT schema (really)

DT schema expects TLMM pin configuration nodes to be named with
'-state' suffix and their optional children with '-pins' suffix.

I already tried to do this in commit d801357a ("arm64: dts: qcom:
sc7280: align TLMM pin configuration with DT schema") and I missed the
fact that these nodes were not part of "state" node.  Bindings did not
catch these errors due to its own issues.
