[PATCH v3] drm/amd/display: Remove unnecessary casts in amdgpu_dm_helpers.c

[Srinivasan Shanmugam]

Fixes the following category of checkpatch complaints:

WARNING: unnecessary cast may hide bugs, see http://c-faq.com/malloc/mallocnocast.html
+               char *buf = (char *)kvcalloc(total, sizeof(char), GFP_KERNEL);

v3:
 - Keeping same as v1 - so that variable "buf" remains to local to the block,
   whereever it is declared, by having just removed the casting.
