docs: devlink: remove the references to sja1105

The sja1105 driver has removed its devlink params, so there is nothing
to see here.

-sja1105 devlink support
-=======================
-
-This document describes the devlink features implemented
-by the ``sja1105`` device driver.
-
-Parameters
-==========
-
-.. list-table:: Driver-specific parameters implemented
-  :widths: 5 5 5 85
-
-  * - Name
-    - Type
-    - Mode
-    - Description
-  * - ``best_effort_vlan_filtering``
-    - Boolean
-    - runtime
-    - Allow plain ETH_P_8021Q headers to be used as DSA tags.
-
-      Benefits:
-
-      - Can terminate untagged traffic over switch net
-        devices even when enslaved to a bridge with
-        vlan_filtering=1.
-      - Can terminate VLAN-tagged traffic over switch net
-        devices even when enslaved to a bridge with
-        vlan_filtering=1, with some constraints (no more than
-        7 non-pvid VLANs per user port).
-      - Can do QoS based on VLAN PCP and VLAN membership
-        admission control for autonomously forwarded frames
-        (regardless of whether they can be terminated on the
-        CPU or not).
-
-      Drawbacks:
-
-      - User cannot use VLANs in range 1024-3071. If the
-	switch receives frames with such VIDs, it will
-	misinterpret them as DSA tags.
-      - Switch uses Shared VLAN Learning (FDB lookup uses
-	only DMAC as key).
-      - When VLANs span cross-chip topologies, the total
-	number of permitted VLANs may be less than 7 per
-	port, due to a maximum number of 32 VLAN retagging
-	rules per switch.
