net: enetc: move enetc_set_psfp() out of the common enetc_set_features()

[ Upstream commit fed38e64d9b99d65a36c0dbadc3d3f8ddd9ea030 ]

The VF netdev driver shouldn't respond to changes in the NETIF_F_HW_TC
flag; only PFs should. Moreover, TSN-specific code should go to
enetc_qos.c, which should not be included in the VF driver.
