[PATCH] soc: mediatek: Use devm_kcalloc() in init_scp()

[SF Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Wed, 26 Apr 2017 18:33:15 +0200

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.
