bsp: cvitek: fix c906_little IRQ_MAX_NR error num

Analysis: The IRQ_MAX_NR value of c906_little is wrong. interrupt.h relies on IRQ_MAX_NR defined in rtconfig.h but does not explicitly include this header file. Solution: Change IRQ_MAX_NR to the correct value 61 in the datasheet. Explicitly include rtconfig.h in interrupt.h.
