PCI: qcom: Add support for parsing the new Root Port binding
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.
