habanalabs: pass-through request from user to f/w
Add a uAPI, as part of the INFO IOCTL, to allow users to send
requests directly to f/w, according to a pre-defined set of opcodes
that the f/w exposes.
The f/w will put the result in a kernel-allocated buffer, which the
driver will then copy to the user-supplied buffer.
This will allow f/w tools to communicate directly with the f/w
without the need to add a new uAPI to the driver for each new type
of request.
