Revert whitespaces to release0.51 (#84)

* Revert whitespaces to release0.51

Some changes between release0.51 and pydppl branch contains unnecessary
modifications of whitespaces. This commit revers whitespace changes to
release0.51.

* Removed unused imported packages

numba/core/codegen.py imported sys.
numba/core/decorators.py imported numba.core.cpu_dispatcher.

* Revert change in comment for releated to CUDA

This comment contains OCL peviously. Then we changed it to DPPy, then to
DPPL and finally release0.51 branch does not contain OCL at all.
