2024-03-01superio/acpi: Add SUPERIO_PNP_NO_DIS to support always active LDNsMichał Żygowski
Some LDNs do not implement the activate bit at all, e.g. ITE GPIO LDNs are an example where the LDN is always active. The pnp_generic.asl can be used to describe the GPIO LDN resources configured by the platform, however the register 0x30 is always 0 for these LDNs, so OS will not claim the reported resource for the GPIO device, because _STA will return inactive LDN. Add SUPERIO_PNP_NO_DIS macro to generate _STA method returning an always active LDN and skip _DIS generation. Define the SUPERIO_PNP_NO_DIS for SIOs which use the pnp_generic.asl preserving the previous states, except the ITE GPIO LDNs.
