PCI: qcom: Don't wait for link if we can detect Link Up
If we have a 'global' IRQ for Link Up events, we need not wait for the
link to be up during PCI initialization, which reduces startup time.
Check for 'global' IRQ, and if present, set 'use_linkup_irq',
so dw_pcie_host_init() doesn't wait for the link to come up.
