While I see the logic in doing this in the autoneg path, if you look
at mtk_pcs_config(), you'll notice that this code you're adding is
unreachable.

If interface is PHY_INTERFACE_MODE_2500BASEX, then we will call
mtk_pcs_setup_mode_force(). We only call mtk_pcs_setup_mode_an() for
the PHY_INTERFACE_MODE_SGMII case when in-band mode is selected, so
this can become:

	regmap_read(mpcs->regmap, mpcs->ana_rgc3, &val);
	val &= ~RG_PHY_SPEED_MASK;
	regmap_write(mpcs->regmap, mpcs->ana_rgc3, val);

Thanks.
