[Patrick Rudolph (Code Review)]

Hello Morgan Jang, Johnny Lin, David Hendricks, Christian Walter, build bot (Jenkins), Andrey Petrov,

to look at the new patch set (#5).

Change subject: acpigen: Add function to generate unicode names

acpigen: Add function to generate unicode names

The ACPI spec 6.3 chapter 6.1.10 states that _STR has to return a buffer
containing UTF-16 characters.

Add function to generate Unicode names and use if for _STR. It will
replace non-ASCII characters with '?'.

Use the introduced function in IPMI driver.

Fixes ACPI warning shown in fwts.
