Thanks for your work.

As the video encoder/decoder driver (vidc) for apq8084 && msm8974 also
use the ocmem for scratch buffers, it might be better to relocate the
ocmem driver in drivers/soc/qcom from the beginning?

I'm working on vidc driver upstream version so it will be nice to test
ocmem driver from it, too.
