properties from the PCIe controller node\nto the Root Port child node, which is required for pwrctrl framework.\nAffected boards:\n- i.MX6Q/DL SABRESD\n- i.MX6SX SDB\n- i.MX8MM EVK\n- i.MX8MP EVK\n- i.MX8MQ EVK\n- i.MX8DXL/QM/QXP EVK\n- i.MX95 15x15/19x19 EVK\n\nThe driver maintains legacy regulator handling for device trees that\nhaven't been updated yet.
