cudaErrorNotSupported when calling cv::cuda::cudaHostRegister on NVIDIA TX2

Hi,

cudaHostRegister() is not supported on ARM platforms.
This is because the caching attribute of an existing allocation can’t be changed on the fly.

If required, please use cudaHostAlloc() with the flag cudaHostAllocMapped to allocate device-mapped host-accessible memory.
Thanks.
