[v1,0/2] Skip waiting for link up during probe

Message

When the Root Complex is probed, the default behavior is to spin in a loop
waiting for the link to come up. In some systems the link is not brought up
during probe, but later in the context of an end-point turning on. This
patch adds a device tree property to the Synopsis designware root
controller to skip this loop.
