As the wait for linkup is removed if there is a global IRQ support,
there is no guarantee that the correct icc and opp votes are updated
as part of probe.

And also global IRQ is being used as hotplug event in case link hasn't
come up as part probe, link up IRQ is the correct place to update the
ICC and OPP votes.

So, as part of the PCIe link up event, update ICC and OPP values.

Fixes: 4581403f6792 ("PCI: qcom: Enumerate endpoints based on Link up event in 'global_irq' interrupt")
