Subject: [PATCH 27/38] arm64: dts: mediatek: mt7988a: Fix PCI-Express T-PHY node address

The PCIe and USB TPHYs are 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 both the tphy(s) 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: ("f693e6ba55ae arm64: dts: mediatek: mt7988: Add t-phy for ssusb1")
