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.
