ACPI: Introduce acpi_set_device_status()
Introduce a static inline function for setting the status field
of struct acpi_device on the basis of a supplied u32 number,
acpi_set_device_status(), and use it instead of the horrible
horrible STRUCT_TO_INT() macro wherever applicable. Having done
that, drop STRUCT_TO_INT() (and pretend that it has never existed).
