e1000e: provide family-specific PHY power up/down operations

The different families (80003es2lan, 8257x, ICHx/PCH) supported by the
driver each have their own conditions when the PHY can be powered down.
This patch rewrites the PHY power up/down code to fit with the family-
specific style used in the driver.  All pre-existing calls to power up or
down the PHY remain untouched.  A new call to power down the PHY when
removing the driver when the interface is down replaces the current call
to reset the PHY in order to reduce power consumption.
