e1000: Esb2 wol link cycle bug and uninitialized registers

Esb2 link didn't return after wol disable. The code previously assumed
that writing reset to PHY_CTRL phy register turned the phy back on.
In the ESB2 phy case that didn't occur.

Add ESB2 to acquire/release_hw functions upon review it was
discovered that esb2 was skipped on these functions
