drm/amd/powerplay: Don't cast kzalloc() return value

The kzalloc function returns a void pointer and the assignment
operator converts it to the type of pointer it is assigned to.
Therefore, there is no need to cast.

Issue found by alloc_cast.cocci:
* WARNING: casting value returned by memory allocation function
to <struct type> is useless.
