Wei Fang 1748531839 net: enetc: VFs do not support HWTSTAMP_TX_ONESTEP_SYNC

[ Upstream commit a562d0c4a8 ]

Actually ENETC VFs do not support HWTSTAMP_TX_ONESTEP_SYNC because only
ENETC PF can access PMa_SINGLE_STEP registers. And there will be a crash
if VFs are used to test one-step timestamp, the crash log as follows.

[  129.110909] Unable to handle kernel paging request at virtual address 00000000000080c0
