[PATCH 24/34] arm64: dts: qcom: sc8180x: Move PCIe phy and GPIOs to root port node

[Krishna Chaitanya Chundru <krishna.chundru@oss.qualcomm.com>]

The PCIe phy reference and the perst/wake GPIO properties are
per root port and belong in the root port node (pcie@0), not in the
RC controller node. Move phys and phy-names from the controller to
pcie0_port0, pcie1_port0, pcie2_port0, and pcie3_port0, adding
labels to these nodes to allow board-level overrides. Move
perst-gpios/wake-gpios from the controller overrides to the
respective port nodes in the board files, renaming perst-gpios to
reset-gpios to match the binding used in the root port context.
