ACPI: misc cleanups

    This patch contains the following possible cleanups:
    - make the following needlessly global code static:
      - drivers/acpi/bay.c:dev_attr_eject
      - drivers/acpi/bay.c:dev_attr_present
      - drivers/acpi/dock.c:dev_attr_docked
      - drivers/acpi/dock.c:dev_attr_flags
      - drivers/acpi/dock.c:dev_attr_uid
      - drivers/acpi/dock.c:dev_attr_undock
      - drivers/acpi/pci_bind.c:acpi_pci_unbind()
      - drivers/acpi/pci_link.c:acpi_link_lock
      - drivers/acpi/sbs.c:acpi_sbs_callback()
      - drivers/acpi/sbshc.c:acpi_smbus_transaction()
      - drivers/acpi/sleep/main.c:acpi_sleep_prepare()
    - #if 0 the following unused global functions:
      - drivers/acpi/numa.c:acpi_unmap_pxm_to_node()
    - remove the following unused EXPORT_SYMBOL's:
      - acpi_register_gsi
      - acpi_unregister_gsi
      - acpi_strict
      - acpi_bus_receive_event
      - register_acpi_bus_type
      - unregister_acpi_bus_type
      - acpi_os_printf
      - acpi_os_sleep
      - acpi_os_stall
      - acpi_os_read_pci_configuration
      - acpi_os_create_semaphore
      - acpi_os_delete_semaphore
      - acpi_os_wait_semaphore
      - acpi_os_signal_semaphore
      - acpi_os_signal
      - acpi_pci_irq_enable
      - acpi_get_pxm
