[PATCH 1/7] dt-bindings: phy: Add document for ASPEED PCIe PHY

[Jacky Chou <jacky_chou@aspeedtech.com>]

Add device tree binding YAML documentation for the ASPEED PCIe PHY.
This schema describes the required properties for the PCIe PHY node,
including compatible strings and register space, and provides an
example for reference.

+description: |
+  The ASPEED PCIe PHY provides the physical layer interface for PCIe
+  controllers in the SoC. This node represents the register block for the PCIe
+  PHY, which is typically accessed by PCIe Root Complex or Endpoint drivers
+  via syscon.
