[PATCH linu-next v1] PCI: dw-rockchip: Enable async probe by default

[Anand Moon <linux.amoon@gmail.com>]

Rockchip PCIe driver lets waits for the combo PHY link like PCIe 3.0,
PCIe 2.0 and SATA 3.0 controller to be up during the probe this
consumes several milliseconds during boot.

Establishing a PCIe link can take a while; allow asynchronous probing so
that link establishment can happen in the background while other devices
are being probed.
