google/kahlee/acpi: Serialize method _CRS

ASL+ Optimizing Compiler/Disassembler version 20170831 shows the remark
below.

```
dsdt.aml     87:  Method (_CRS, 0x0, NotSerialized)
Remark   2120 -             ^ Control Method should be made Serialized \
        (due to creation of named objects within)
```

So, serialize the method.
