Enable the 2 Cache Controller (L2CC) is based on the L2CC-PL310 ARM
multi-way cache macrocell, version r3p2. The addition of an on-chip
secondary cache, also referred to as a Level 2 or L2 cache, is a
method of improving the system performance when significant memory
traffic is generated by the processor.

This choice specifies the associativity of L2 cache in terms of the
number of ways. This value could be obtained by querying cache
configuration registers. However, by defining a configuration
setting instead, we can avoid using RAM memory to hold information
about properties of the memory.
