[PATCH 2/2] ACPI: Remove unused lockable in acpi_device_flags

[Toshi Kani]

Removed lockable in struct acpi_device_flags since it is no
longer used by any code. acpi_bus_hot_remove_device() cannot
use this flag because acpi_bus_trim() frees up its acpi_device
object. Furthermore, the dock driver calls _LCK method without
using this lockable flag.
