Subject: [RFC PATCH v2 linux-next 14/14] net: dsa: sja1105: add support for the SJA1110 SGMII/2500base-x PCS

Configure the Synopsys PCS for 10/100/1000 SGMII in autoneg on/off
modes, or for fixed 2500base-x.

The portion of PCS configuration that forces the speed is common, but
the portion that initializes the PCS and enables/disables autoneg is
different, so a new .pcs_config() method was introduced in struct
sja1105_info to hide away the differences.

For the xMII Mode Parameters Table to be properly configured for SGMII
mode on SJA1110, we need to set the "special" bit, since SGMII is
officially bitwise coded as 0b0011 in SJA1105 (decimal 3, equal to
XMII_MODE_SGMII), and as 0b1011 in SJA1110 (decimal 11).
