drivers/gpu/arm/utgard: add basic HiKey platform files

Add Mali Utgard GPU driver platform files to support the
HiKey board (HI6220), based on the Balong platform.

Note: GPU DVFS is not implemented and a custom Device Tree
      entry is needed by these platform files.  This is a
      first working version that needs to be improved.
