XPCS IP supports 2500BASEX as PHY interface. It is configured as
autonegotiation disable to cater for PHYs that does not supports 2500BASEX
autonegotiation.
v2: Add supported link speed masking.
v3: Restructure to introduce xpcs_config_2500basex() used to configure the
xpcs for 2.5G speeds. Added 2500BASEX specific information for
configuration.
v4: Fix indentation error
