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.
