LPC32XX architecture files (updated)

[wellsk40 at gmail.com]

The initial LCP32xx arch files are in these patches. Changes from
yesterdays posting:

gpiolib.c updated from user review comments, thanks!

Files all send via git send-email now, thanks for pointing me in
the right direction and sorry about the wraps. (if gmail wasn't
available, I'd be stuck!)

These have been checked with checkpatch.

thanks,
