net: enetc: move enetc_set_si_vlan_promisc() to enetc_pf_common.c

Browse source 
The PSIPVMR in ENETC v4 has the same bit layout and functionality as the
PSIPVMR register in ENETC v1: bit n (n <= 15) controls VLAN promiscuous
mode for SI n. The only difference between the two hardware generations
is the register address offset.

Since the register functionality is identical, the VLAN promiscuous mode
setting code can be shared between ENETC v1 and v4 drivers.

Move enetc_set_si_vlan_promisc() from enetc_pf.c to enetc_pf_common.c
and export it so that it can be shared between the two drivers. Add a
revision check using is_enetc_rev1() to select the correct register
offset (ENETC_PSIPVMR for v1 and ENETC4_PSIPVMR for v4) while keeping
the same logic.

Remove the v4-specific enetc4_pf_set_si_vlan_promisc() from enetc4_pf.c
and replace its call site with the new common enetc_set_si_vlan_promisc()
to eliminate code duplication.
