When suspending the machine, do not shutdown the external PHY by cutting
its regulator in the mac platform driver suspend code if Wake-on-Lan is enabled,
else it cannot wake us up.
In order to do this, split the suspend/resume callbacks from the
init/exit callbacks, so we can condition the power-down on the lack of
need to wake-up from the LAN but do it unconditionally when unloading the
module.

Let the stmmac platform drivers provide dedicated suspend and resume
callbacks rather than always re-using the init and exits callbacks.
If the driver does not provide the suspend or resume callback, we fall
back to the old behavior trying to use exit or init.

This allows a specific platform to perform only a partial power-down on
suspend if Wake-on-Lan is enabled but always perform the full shutdown
sequence if the module is unloaded.

If it is not supported we simply disable the feature.

For the feature to work we need firmware filter support for
OUTER_VID + LOC_MAC and for OUTER_VID + LOC_MAC_IG.
The low-latency firmware can match on OUTER_VID + LOC_MAC but not on
OUTER_VID + LOC_MAC_IG.
For the capture packet firmware it is the other way around.
Only the full-feature variant can match on both combinations.

When trying to enslave an SFC interface to a bond the following BUG_ON was
hit:

 kernel BUG [in ef10.c]!
 CPU: 0 PID: 4383 Comm: ifenslave Tainted: G
...
 Call Trace:
  efx_ef10_filter_add_vlan+0x121/0x180 [sfc]
  efx_ef10_filter_table_probe+0x2a2/0x4f0 [sfc]

  efx_set_mac_address+0x7d/0x120 [sfc]
  dev_set_mac_address+0x43/0xa0
  bond_enslave+0x337/0xea0 [bonding]
This comes from function efx_ef10_filter_vlan_sync_rx_mode.

To solve the bug we ensure the mac_lock is taken before calling
efx_ef10_filter_add_vlan. But to avoid a priority inversion mac_lock must
be taken before filter_sem.
To satisfy these requirements we end up taking mac_lock in
efx_ef10_vport_set_mac_address, efx_ef10_set_mac_address,
efx_ef10_sriov_set_vf_vlan and efx_probe_filters.
