Subject: arm64: dts: rockchip: Enable PCIe 2 on SOQuartz CM4IO
Origin: https://git.kernel.org/linus/3736aa7ecc4cd9b4abce30052bad00aba4f0362f
This patch enables the PCIe2 on the CM4IO board when paired with
a SOQuartz CM4 System-on-Module board. combphy2 also needs to be
enabled in this case to make the PHY work for this.
