In cases where a global IRQ handler is present to manage link up
interrupts, it may not be necessary to wait for the link to be up
during PCI initialization which optimizes the bootup time.

So, set linkup_irq flag if global IRQ is present and In order to set the
linkup_irq flag before calling dw_pcie_host_init() API, which waits for
link to be up, move platform_get_irq_byname_optional() API
above dw_pcie_host_init().
