There are two bugs in the CAN driver for the LPC2xxx.

One is in include/can_lpc2xxx_baudrates.h: numbers shouldn't be prefixed
with 0 if they aren't intended to be interpreted as octal. I fixed this
only where it actually breaks, but the rest should be changed, too.

The other is in src/can_lpc2xxx.c, the definition of "info" is missing
when only one CAN channel is configured.

Hello Hans,

----->
I've noticed another strange thing, is there a specific reason that
tests/can_baudrates.c, tests/can_busload.c and tests/can_rx_tx.c all
#include pkgconf/devs_can_loop.h?
<----

This is simply a copy & paste issue. I forgot to remove these lines. You 
can remove them and create a patch.

Thank you.
