Stacey Sheldon 8b0415d905 bl: alternate stopwatch for small bootloaders
The small bootloaders (CC and PipX) are out of flash space
so their stopwatch implementation has been swapped out for
one based on the DELAY clock that takes about 500 bytes less
of code space.

Identical functionality is preserved.
