[ Upstream commit c32fe1986f27cac329767d3497986e306cad1d5e ]
FEC_ECR_EN1588 bit gets cleared after MAC reset in `fec_stop()`, which
makes all 1588 functionality shut down, and all the extended registers
disappear, on link-down, making the adapter fall back to compatibility
"dumb mode". However, some functionality needs to be retained (e.g. PPS)
even without link.
Fixes: 6605b730c061 ("FEC: Add time stamping code and a PTP hardware clock")
