[PATCH 1/6] GPU-DRM-GMA500: Use kmalloc_array() in mid_get_vbt_data_r10()

A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus use the corresponding function "kmalloc_array".

This issue was detected by using the Coccinelle software.
