Merge branch 'net-phy-shrink-PHY-settings-array-and-add-200Gbps-support' 

Heiner Kallweit says:

====================
net: phy: shrink PHY settings array and add 200Gbps support

The definition of array settings[] is quite lengthy meanwhile. Add a
macro to shrink the definition.

When doing this I saw that the new 200Gbps modes and few 100Gbps/50Gbps
modes aren't supported in phylib yet. So add this.

To avoid ethtool and phylib mode definitions getting out of sync, add
a build bug to check for this.
