[PATCH v1 3/5] gpiolib: acpi: Reduce memory footprint for struct acpi_gpio_params

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

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.

`pahole` difference before and after:

-	/* size: 12, cachelines: 1, members: 3 */
-	/* padding: 3 */

+	/* size: 8, cachelines: 1, members: 3 */
+	/* padding: 1 */
