[PATCH 1/9] PCI ACPI: Remove acpi_platform_enable_wakeup

PCI ACPI: Remove acpi_platform_enable_wakeup

This patch removes "Fix forcedeth hibernate/wake-on-lan problems",
commit f5ccbcfacaae57e3312e623432a79d5f1f079cf5 in linux-next,
which is incorrect, because it directly manipulates the
wakeup.state.enabled flags of ACPI devices while these flags are
supposed to be used by the user space to control wake-up.  Moreover,
it affects not only the device it is supposed to fix (forcedeth), but
also every PCI device that happens to call
device_init_wakeup(dev, 1).

Apart from this, it has been pushed as a network driver fix, while it should
have gone through either ACPI or PCI tree.  Also, the other patches in this
series are intended to fix the issue it was supposed to fix, but in a more
complete way.
