This PR adds support for the optimized Xtensa max and average pool kernels when using 16-bit activations and 8-bit weights. Previously, this configuration would fall back to the reference implementation.

Changes:

  • Created new 'pooling_hifi.cc' file which contains implementations of max and average pooling for both 8-bit and 16-bit inputs
  • Removed old 'pooling_int8.cc' file

bug=fixes #3482

Hi @rameshkunasi, I think I spotted the issue that caused the tests to fail. Could you approve the execution of the CI/CD test suite again?

Cheers.
