gpio: pca953x: add a comment explaining the need for a lockdep subclass
This is a follow-up to commit 559b46990e76 ("gpio: pca953x: fix an
incorrect lockdep warning"). The reason for calling
lockdep_set_subclass() in pca953x_probe() is not explained in
the code.
Add a comment describing the problem, partial solution and required
future extensions.
