[PATCH net-next] net: dsa: sja1105: allow the TTEthernet configuration in the static config for SJA1110

[Vladimir Oltean]

From: Vladimir Oltean <vladimir.oltean@nxp.com>

Currently sja1105_static_config_check_valid() is coded up to detect
whether TTEthernet is supported based on device ID, and this check was
not updated to cover SJA1110.

However, it is desirable to have as few checks for the device ID as
possible, so the driver core is more generic. So what we can do is look
at the static config table operations implemented by that specific
switch family (populated by sja1105_static_config_init) whether the
schedule table has a non-zero maximum entry count (meaning that it is
supported) or not.
