The Root Complex specific device tree binding for pcie-dw-rockchip has the 'sys' interrupt marked as required. The driver requests the 'sys' IRQ unconditionally, and errors out if not provided. Thus, we can unconditionally set use_linkup_irq before calling dw_pcie_host_init(). This will skip the wait for link up (since the bus will be enumerated once the link up IRQ is triggered), which reduces the bootup time.
