====================
r8169: factor out chip-specific PHY configuration to a separate source file

Basically every chip version needs its own PHY configuration.
To improve maintainability of the driver move all these PHY
configurations to a separate source file. To allow this we first have
to change all PHY configurations to use phylib functions wherever
possible.
