x86/acpigen: Fix ACPI _ROM method

================================================================================
ADVICE: (for Remark #2120, ASL_MSG_SERIALIZED_REQUIRED): A named object is
created inside a non-serialized method - this method should be serialized. It is
possible that one thread enters the method and blocks and then a second thread
also executes the method, ending up in two attempts to create the object and
causing a failure.
Use the acpigen_write_method_serialized() to correct the error.
BUG=b:112476331
TEST=Run FWTS.
