-- General configuration for OpenCV 4.4.0-pre =====================================
--   Version control:               4.3.0-464-g5ed6546
-- 
--   Extra modules:
--     Location (extra):            /opencv_contrib/modules
--     Version control (extra):     4.3.0-69-g0f56e6d
 :
-- CUDA detected: 8.0
-- Automatic detection of CUDA generation failed. Going to build for all known architectures.
-- CUDA NVCC target flags: -ccbin;/usr/bin/cc;-gencode;arch=compute_53,code=sm_53;-gencode;arch=compute_62,code=sm_62;-gencode;arch=compute_72,code=sm_72;-D_FORCE_INLINES

The "Automatic detection" usually successes, but it fails, after #17526
Also, sm72 is added, but TX1 and TX2 has CUDA 8.0, which doesn't know anything about sm72.

As a result, it fails compiling

nvcc fatal   : Unsupported gpu architecture 'compute_72'
CMake Error at cuda_compile_1_generated_gpu_mat.cu.o.Release.cmake:219 (message):
  Error generating
  /opencv/build/modules/core/CMakeFiles/cuda_compile_1.dir/src/cuda/./cuda_compile_1_generated_gpu_mat.cu.o

I'm not sure why the automatic detection fails, but wiping out the non-supported CC should let workaround this issue.

Steps to reproduce

Issue submission checklist

• I report the issue, it's not a question
• I checked the problem with documentation, FAQ, open issues,
  answers.opencv.org, Stack Overflow, etc and have not found solution
• I updated to latest OpenCV version and the issue is still there
• There is reproducer code and related data files: videos, images, onnx, etc
