The 'commit 4581403f6792 ("PCI: qcom: Enumerate endpoints based on Link up
event in 'global_irq' interrupt")' added the Link up based enumeration
support failed to update the ICC/OPP vote once link is up. Earlier, the
update happens during probe and the endpoints may or may not be enumerated
at that time. So the ICC/OPP vote was not guaranteed to be accurate. Now
with the Link up based enumeration support, the driver can request the
accurate vote based on the PCIe link.
So call qcom_pcie_icc_opp_update() in qcom_pcie_global_irq_thread() after
enumerating the endpoints.
