ACPI: call acpi_sleep_proc_init() explicitly rather than as initcall

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).
