Drivers should go in the proper place if it all possible. For example,
for Pika's warp, the watchdog driver is in the watchdog directory
(drivers/watchdog/pika_wdt.c) even though it is FPGA based and very
specific to the warp.

However, the LEDS where put in arch/powerpc/platforms/44x/warp.c. So it
is in the platform code. I also put our FPGA based DTM (Dynamic Thermal
Management) in the warp.c file.

If you submit the code... the reviewers will make recommendations on
where it should go.
