e1000e: ICHx/PCHx LOMs should use LPLU setting in NVM when going to Sx
When going to Sx with an ICHx/PCH device, the default Low Power Link Up (LPLU, a.k.a. reverse auto-negotiation) behavior should be whatever is set in the NVM. However, the function e1000_suspend_workarounds_ich8lan() called when going to Sx always enabled LPLU in all power states.
