#if 0-out a half-fixed acpi_eval_string() and #if 0 the only call to it.
(Previous code referenced an uninitialized local variable and couldn't

- In acpi_print(), try to evaluate the _STR object, and print
it if the device is not configured.
- Make this compile without ACPI_DEBUG, from Masanori Kanaoka.
