Change Details

The pic_* interface was used. Only edge interrupts are supported by this controller. Driver mutex had to be converted to a spin lock so that it cal be used in the interrupt filter context. Two types of intr_map_data are supported - INTR_MAP_DATA_GPIO and INTR_MAP_DATA_FDT. This way interrupts can be allocated using the userspace gpio interrupt allocation method, as well as directly from simplebus. The latter can be used by devices that have its irq routed to a GPIO pin.

Expose softc and other necessary things in a separate header. This is needed for an armv8 specific driver, that will inherit from this one. Driver mutex was converted to a spin lock, so that it can be later used in interrupt filter context.
