[PATCH] powermac: Fix loss of ethernet PHY on sleep

Some recent PowerBook models tend to lose the ethernet PHY on
suspend/resume.  It -seems- that they use a combo ethernet-firewire PHY
chip and the firewire PHY seems to die the same way when that happens.  Not
trying to toggle the firewire cable power appears to fix it.  So this patch
disables changes to the firewire cable power control GPIO on those models.
