ACPI: call init_acpi_device_notify() explicitly rather than as initcall
This patch makes acpi_init() call init_acpi_device_notify() directly.
Previously, init_acpi_device_notify() was an arch_initcall (sequence 3),
so it was called before acpi_init() (a subsys_initcall at sequence 4).
init_acpi_device_notify() sets the platform_notify and
platform_notify_remove function pointers. These pointers
are not used until acpi_init() enumerates ACPI devices in
this path:
acpi_init()
acpi_scan_init()
acpi_bus_scan()
acpi_add_single_object()
acpi_device_register()
device_add()
<use platform_notify>
So it is sufficient to have acpi_init() call init_acpi_device_notify()
directly before it enumerates devices.
