Use the new asynchronous IRQ interface in the mostly used drivers, e.g.: * ahci_drv: x86/exynos5 * gpio_drv: imx53/omap4 * input_drv: imx53/dummy * ps2_drv: x86/pl050 * timer_drv Now, the Irq_session is requested from Gpio::Session: From now on we use an asynchronous IRQ interface. To prevent triggering another GPIO IRQ while currently handling the former one, IRQs must now by acknowledged explicitly. While here, we also changed the GPIO session interface regarding IRQ management. The generic GPIO component now wraps the Irq_session managed by the backend instead of using the GPIO backend methods directly. A client using the GPIO session may request the Irq_session_capability by calling 'Gpio::Session::irq_session()' and can use this capability when using a local Irq_session_client. Issue #1456.
