[PATCH v2 06/15] arm64: dts: qcom: sdm845: Move PCIe phy and GPIOs to root port node

[Krishna Chaitanya Chundru]

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 and pcie1_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.
