net: pcs: xpcs: add CL37 1000BASE-X AN support
For CL37 1000BASE-X AN, DW xPCS does not support C22 method but offers
C45 vendor-specific MII MMD for programming.
We also add the ability to disable Autoneg (through ethtool for certain
network switch that supports 1000BASE-X (1000Mbps and Full-Duplex) but
not Autoneg capability.
v4: Fixes to comment from Russell King. Thanks!

Make xpcs_modify_changed() as private, change to use
mdiodev_modify_changed() for cleaner code.
v3: Fixes to issues spotted by Russell King. Thanks!
https://patchwork.kernel.org/comment/24890210/
Use phylink_mii_c22_pcs_decode_state(), remove unnecessary
interrupt clearing and skip speed & duplex setting if AN
is enabled.
v2: Fixes to issues spotted by Russell King in v1. Thanks!
https://patchwork.kernel.org/comment/24826650/
Use phylink_mii_c22_pcs_encode_advertisement() and implement
C45 MII ADV handling since IP only support C45 access.
