e1000e: do not touch PHY page 800 registers when link speed is 1000Mbps

The PHY on 82577/82578 has issues when the registers on page 800 are
accessed when in gigabit mode.  Do not clear the Wakeup Control register
when resetting the part since it is on page 800 (and will be cleared on
reset anyway).
