[PATCH 2/2] of_coresight: Use devm_kcalloc() in of_coresight_alloc_memory()

From: SF Markus Elfring

Multiplications for the size determination of memory allocations
indicated that array data structures should be processed.
Thus use the corresponding function "devm_kcalloc".

This issue was detected by using the Coccinelle software.
