arm64: dts: mediatek: mt7986a: Fix PCI-Express T-PHY node address

The PCIe TPHY is under the soc bus, which provides MMIO, and all
nodes under that must use the bus, otherwise those would clearly
be out of place.

Add ranges to the PCIe tphy and assign the address to the main
node to silence a dtbs_check warning, and fix the children to
use the MMIO range of t-phy.

Fixes: 963c3b0c47ec ("arm64: dts: mediatek: fix t-phy unit name")
Fixes: 918aed7abd2d ("arm64: dts: mt7986: add pcie related device nodes")
