[PATCH net-next v2 10/10] net: phy: marvell10g: add support for the 88x2110 PHY

[Maxime Chevallier]

This patch adds support for the 88x2110 PHY, which is similar to the
already supported 88x3310 PHY without the SFP interface.

It supports 10/100/1000BASET along with 2.5GBASET, 5GBASET and 10GBASET,
with the same interface modes that are used by the 3310.

This PHY don't have the same issue as the 88x3310 regarding 2.5/5G
abilities, and correctly follows the 802.3bz standard to list the
supported abilities.

V1 -> V2: Use a #define for the PHY ID, since we also do that for the
          3310. Removed the mv2110_config_init implementation since we
          now manually check for the PMA device id when using the quirk.
