Driver Core: add ability for class_find_device to start in middle of list

Browse Source 
This mirrors the functionality that driver_find_device has as well.

We add a start variable, and all callers of the function are fixed up at
the same time.

The block layer will be using this new functionality in a follow-on
patch.
