Subject: net: fec: enable to use PPS feature without time stamping
Git-commit: e53a57e56fce787ee4d02ffc2cf9ba46f0173f58
Patch-mainline: v5.9-rc1
References: jsc#SLE-16106

PPS feature could be useful even when hardware time stamping
of network packets is not in use, so remove offending check
for this condition from fec_ptp_enable_pps().
