In RZ/N1 SoC family, a h2mode setting is available to change the USB configuration from one host and one device to two hosts. This change will be done at sysctrl level and must not be done while USB host or device are running. In order to express this dependency (probe order dependency), introduce 'depends-on' property at PCI bridge level.
