Verified this on Taniks.

I can see the newly added _DSM for `USB3 Type-C Port C1 (DB)` where `register "usb_lpm_incapable" = "true"` was added.

```
        Method (_DSM, 4, Serialized)  // _DSM: Device-Specific Method
        {
            ToBuffer (Arg0, Local0)
            If ((Local0 == ToUUID ("ce2ee385-00e6-48cb-9f05-2edb927c4899") /* USB Controller */))
            {
                ToInteger (Arg2, Local1)
                If ((Local1 == Zero))
                {
                    Return (Buffer (One)
                    {
                         0x21                                             // !
                    })
                }

If ((Local1 == One)){}
                If ((Local1 == 0x02)){}
                If ((Local1 == 0x03)){}
                If ((Local1 == 0x04)){}
                If ((Local1 == 0x05))
                {
                    Return (0x01)
                }

Return (Buffer (One)
                {
                     0x00                                             // .
                })
            }

Return (Buffer (One)
            {
                 0x00                                             // .
            })
        }
```
