AWQ does not support Turing GPUs

[WoosukKwon]

          @WoosukKwon Doesn't it support Turing arch? my GPU's compute capabitlity is 7.5. CUDA-12.1.

build Error message:

ptxas /tmp/tmpxft_0006e7c4_00000000-6_gemm_kernels.ptx, line 928; error : Feature '.m16n8k16' requires .target sm_80 or higher

If not, hope can add backward compatibility for kernel build.
