The gpgpu fill utility functions are used in separate test so it's
logical to keep them in separate file. This is similar to what media
spin test did in the past.
Functionally only gpgpu kernel changed. Send instruction payload size
was reduced. Since offset is incremented by 0x10 bytes there is no point
in using larger writes.
