e1000e: separate out PHY statistics register updates

Browse source

The 82577/82578 parts have half-duplex statistics in PHY registers.  These
need only be read when in half-duplex and should all be read at once rather
than one at a time to prevent excessive cycles of acquiring/releasing the
PHY semaphore.
