Fix the clock name, too.

And remove an unneeded index in the array-initialization.

Hi Wolfram,
Thanks for submitting these. These all look good!

The LPC32xx user's guide spaces peripheral register sets 16K apart,
but internally the register blocks are 4K or smaller. I'm not sure
why these need to be setup as 16K instead of 4K. Hmm, maybe I'm
missing something here?

Probably not. I just took the user's guide as a reference. If you know this is
wrong, I can respin the series. ADC is also 4K?
Thanks,
Wolfram

Yes, WDT/ADC/RTC are all 4K register blocks.
