The DT binding has moved the PHY, PERST# properties to Root Port node from the Host Bridge node. So add support for parsing the new binding. The new binding uses 'reset-gpios' property for PERST#, hence parse the same property in the driver instead of the legacy 'perst-gpios'. To maintain DT backwards compatibility, fallback to the legacy method of parsing the host bridge node if the properties are not present in the Root Port node.
