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 Signed-off-by: Cliff Huang <cliff.huang@intel.com> Change-Id: I1f4b55a268c1dadbae456afe5821ae161b8e15a5 Reviewed-on: https://review.coreboot.org/c/coreboot/+/77695 Reviewed-by: Eric Lai <eric_lai@quanta.corp-partner.google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Jérémy Compostella <jeremy.compostella@intel.com>
