fsl/pcie: Change 'no link' to 'undetermined' for pcie endpoint
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. The link status can check from host side eventually. Signed-off-by: Roy Zang <tie-fei.zang@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
