drivers/misc is almost always the wrong answer to where to add a driver.
It would help to also know how the devices interact to answer the question of best location. Are the drivers for the coprocessor and for the queue manager mostly a pass-through for some operations (and some shared allocation of resources), i.e. more of a library, or is it a full-fledged driver that will service interrupts, etc?

This depends somewhat on where the driver ends up, but somewhere under include/linux is likely the right place for the in-kernel interface header files.
