gpiolib: acpi: Reduce memory footprint for struct acpi_gpio_params
The line_index member in the struct acpi_gpio_params replicates
what is covered in the ACPI GpioIo() or GpioInt() resource.
The value there is limited to 16-bit one, so we don't really need
to have a full 32-bit storage for it. Together with followed
boolean the structure will be smaller.
