acpi: Comply with ACPI specification by making _STR unicode strings
_STR should return Unicode string. From ACPI spec:
6.1.10 _STR (String)
The _STR object evaluates to an Unicode string that describes the
device or thermal zone.
BUG=NA
TEST=Check the changed _STR in SSDT to see if Unicode() macro is used
