ACPI / gpio: Add irq_type when a GPIO is used as an interrupt
When a GPIO is used as an interrupt in ACPI, the irq_type was not available for device driver. Make available polarity and triggering information in acpi_find_gpio by renaming acpi_gpio_info field active_low to polarity and adding triggering field (edge/level). For sanity, in gpiolib.c replace info.active_low by "info.polarity == GPIO_ACTIVE_LOW". Set the irq_type if necessary in acpi_dev_gpio_irq_get.
