[PATCH v2 6/8] PCI: qcom: Use post init sequence of IP v2.3.2 for v2.4.0

[Manivannan Sadhasivam]

The post init sequence of IP v2.4.0 is same as v2.3.2. So let's reuse the
v2.3.2 sequence which now also disables hotplug capability of the
controller as it is not at all supported on any SoCs making use of this IP.
