Among these interrupts there are the Gigabits Ethernet ones used by the mvneta driver. Unfortunately the state of the percpu_irq API prevents the driver to use it. Indeed the interrupts have to be freed when the .stop() function is called. As the free_percpu_irq() function don't disable the interrupt line, we have to do it on each CPU before calling this. The function disable_percpu_irq() only disable the percpu on the current CPU and there is no function which allows to disable a percpu irq on a given CPU. Waiting for the extension of the percpu_irq API, this fix allows to use again the mvneta driver.

Some kirkwood boards don't use both pins as they are not connected, and don't set the corresponding value in platform_data. This will leave the unset values in platform_data initialized as 0, which is in fact a valid gpio pin. mvsdio will grab that pin and configure it as gpio, which in turn breaks nand controller as mpp0 also carries nand_io2. This patch fixes the above by initializing unused gpio functions in the platform_data with an invalid (-1) value.
