arm64: dts: mediatek: fix t-phy unit name

dtbs_check throws a warning at t-phy nodes:
Warning (unit_address_vs_reg): /t-phy@1a243000: node has a unit name, but no reg or ranges property
Warning (unit_address_vs_reg): /soc/t-phy@11c00000: node has a unit name, but no reg or ranges property

The ranges is empty thus removing the `@1a243000`, `@11c00000` from
the node name.

Fixes: 6029cae6 ("arm64: dts: mediatek: mt7622: harmonize node names and compatibles")
Fixes: 918aed7a ("arm64: dts: mt7986: add pcie related device nodes")
