irq: Allow boards to define the return type of irq_save()
The AVR wants a uint8_t return type for irq_save(), but other architectures will generally prefer int. Allow the board to configure the size of the flag by introducing an irqstatus_t typedef. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
