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 it for _STR. It will
replace non-ASCII characters with '?'.
Use the introduced function in IPMI driver.
Fixes ACPI warning shown in fwts.
