drivers/usb/acpi: acpi_power_res_params: Add use_gpio_for_status
Add the member `use_gpio_for_status` to the structure
`drivers_usb_acpi_config`, so the `devicetree.cb` can specify it.
This field is then used to initialize the corresponding field in the
structure `acpi_power_res_params` in `usb_acpi_fill_ssdt_generator()`.
The member `acpi_power_res_params::use_gpio_for_status()` is already
being used by `acpi_device_add_power_res()` to determine which version
of the `_STA()` method to output.
