[PATCH v2 3/5] arm64: dts: qcom: nord-ride-embedded: Enable PCIe controllers and PHY

[Shawn Guo]

From: Krishna Chaitanya Chundru <krishna.chundru@xxxxxxxxxxxxxxxx>

The Nord Ride Embedded board routes all four PCIe links, so enable
pcie0-pcie3 and the QMP PHY, supply the per-port PHY and PLL rails, and
describe the PERST# and WAKE# lines of each root port.
