[PATCH v2 12/15] arm64: dts: qcom: sm8650: 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
the existing pcieport0 and pcie1_port0, allowing 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.
