### What this PR does / why we need it?
1.Support deepseek w4a8 per-channel quantization
2.The eager mode supports converting weights to the NZ format
### Does this PR introduce _any_ user-facing change?
no

 ### 3. When converting deepseek series models with modelslim, what should you pay attention?
 
-When using the weight generated by modelslim with the `--dynamic` parameter, if torchair graph mode is enabled, please modify the configuration file in the CANN package to prevent incorrect inference results.
+When the mla portion of the weights used `W8A8_DYNAMIC` quantization, if torchair graph mode is enabled, please modify the configuration file in the CANN package to prevent incorrect inference results.
 
 The operation steps are as follows:
 
 1. Search in the CANN package directory used, for example:
 find /usr/local/Ascend/ -name fusion_config.json
