Lpc2000

I finally got the thing to work. I was writing to the wrong address space for the external 
interrupt registers. On exit from power down, I do need to enable PLL again (because I'm 
running at 60Mhz) and since I did not enable the external interrupt, it took quite a while to 
figure out that I still need to clear the int flag or else the cpu won't go to sleep the next 
time. Anyways, FYI.
