ACPI: call acpi_wakeup_device_init() explicitly rather than as initcall
This patch makes acpi_init() call acpi_wakeup_device_init() directly. Previously, acpi_wakeup_device_init() was a late_initcall (sequence 7). acpi_wakeup_device_init() depends on acpi_wakeup_device_list, which is populated when ACPI devices are enumerated by acpi_init() -> acpi_scan_init(). Using late_initcall is certainly enough to make sure acpi_wakeup_device_list is populated, but it is more than necessary. We can just as easily call acpi_wakeup_device_init() directly from acpi_init(), which avoids the initcall magic.
