gpiolib: Update documentation of struct acpi_gpio_info

Browse Source 
It seems the code had been changed, but description left untouched.

Update description of the struct acpi_gpio_info and relative comments
accordingly.

Fixes: commit 52044723cd ("ACPI / gpio: Add irq_type when a GPIO is used as an interrupt")
