zhangxinyuehfad a5b099c73d [Bugfix] Reset incompatible config (#6005 )

### What this PR does / why we need it?
This PR introduces compatibility fixes for running vLLM on Ascend NPU
hardware. The changes ensure that GPU-specific parameters are
automatically detected and reset to Ascend-compatible values with
appropriate warnings logged.
