ACPICA: Add Buffer->String conversion for predefined methods
For predefined methods (such as _BIF), add automatic conversion for
objects that are required to be a String, but a Buffer was found
instead. This can happen when reading string battery data from
an operation region, because it used to be difficult to convert
the data from buffer to string from within the ASL. Linux BZ 11822.
