Even u-boot boots up, the pcie link may not setup correctly when Freescale SOC acts as endpoint. So change the link status from 'no link' to 'undetermined' to reduce the confusion.

As description of commit message saying "The link status can check from host side eventually " It will be good, if we can also print link status at this point to let user know about status of end point.
