mb/lenovo/s230u: Rewrite trigger inversion ACPI code
The GPIO invert registers are already defined in the PCH code, so just use the 8-bit versions of the registers instead of creating a new GPIO field for the single bits. This allows us to get rid of the Field(GPIO...) code that's causing problems with IASL version 20190509.
