net: phy: realtek: map vendor-specific EEE registers to standard MMD registers

EEE-related registers on newer integrated PHY's have the standard
layout, but are accessible not via MMD but via vendor-specific
registers. Emulating the standard MMD registers allows to use the
generic functions for EEE control and to significantly simplify
the r8169 driver.

v2:
- rebase patch 2
