crypto: inside-secure - dynamic ring configuration allocation

Browse Source 
The Inside Secure SafeXcel driver currently uses 4 rings, but the
eip197d engines has 8 of them. This patch updates the driver so that
rings are allocated dynamically based on the number of available rings
supported by a given engine.
