platform/x86: think-lmi: Enable opcode support on BIOS settings

Whilst reviewing some documentation from the FW team on using WMI on
Lenovo system I noticed that we weren't using Opcode support when
changing BIOS settings in the thinkLMI driver.

We should be doing this to ensure we're future proof as the old
non-opcode mechanism has been deprecated.

Tested on X1 Carbon G10 and G11.
