From: farah kassabri <fkassabri@xxxxxxxxx>
The preboot used to statically allocate memory for the comms descriptor
on the device memory when driver requested the descriptor information.
Now preboot moved to dynamic memory allocation where it wants to check
the size the driver expects vs. what the f/w expects.
Note there are no backward compatibility issues as older f/w versions
simply ignore this value.
