Convert acpi_device_lock to a mutex to avoid
a potential race upon access to /proc/acpi/wakeup
Delete the lock entirely in wakeup.c
since it is not necessary (and can not sleep)

ACPI: call acpi_sleep_proc_init() explicitly rather than as initcall2009-03-27T16:51:23ZBjorn Helgaasbjorn.helgaas@hp.com2009-03-24T22:50:14Zurn:sha1:9cee43e07940bee13462e63bd75ce4430b155886
This patch makes acpi_init() call acpi_sleep_proc_init() directly.
Previously, acpi_sleep_proc_init() was a late_initcall (sequence 7),
apparently to make sure that the /proc hierarchy already exists:

acpi sleep: demote sleep proc file creation.
- Make acpi_sleep_proc_init() a late_initcall(), and not called from
acpi_sleep_init(). This guarantees that the acpi proc hierarchy is at
least there when we create the dang file.
This should no longer be an issue because acpi_bus_init() (called early
in acpi_init()) creates acpi_root_dir (/proc/acpi).
