A72 Cluster (chapter 1.3.1 [1]) has 48KB Icache, 32KB Dcache and 1MB L2 Cache
 - ICache is 3-way set-associative
 - Dcache is 2-way set-associative
 - Line size are 64bytes

32KB (Dcache)/64 (fixed line length of 64 bytes) = 512 ways
512 ways / 2 (Dcache is 2-way per set) = 256 sets.

So, correct the d-cache-sets info.
