Subject: [PATCH 1/1] arm64: dts: imx95: add ref clock for pcie nodes

Add "ref" clock for i.MX95's pcie and fix below CHECK_DTBS warnings:
arch/arm64/boot/dts/freescale/imx95-19x19-evk.dtb: pcie@...00000: clock-names: ['pcie', 'pcie_bus', 'pcie_phy', 'pcie_aux'] is too short
	from schema $id: http://devicetree.org/schemas/pci/fsl,imx6q-pcie.yaml
