media: atomisp: remove private acceleration ioctls

Browse source 
These ioctls allow userspace to load custom programs into the ISP, which:

a) Seems dangerous
b) Cannot be used by opensource userspace since there is no FOSS code to
   create such programs
b) These seem to be unused even by the Android closed source camera code
   (they don't show up in a strace of the camera app)

So removing these seems be a good idea. Another reason to remove these is
that atomisp_acc_map() is the only user of the userptr functionality in
hmm_alloc(), so it gets in the way of further cleanups / simplification
of the hmm code.
