Trim `.acpi_fill_ssdt_generator` and `.acpi_inject_dsdt_generator`

These two identifiers were always very confusing. We're not filling and
injecting generators. We are filling SSDTs and injecting into the DSDT.
So drop the `_generator` suffix. Hopefully, this also makes ACPI look a
little less scary.
