Oh, it looks this patch is a stack from the previous one.
This patch also looks good!
I would update the commit message to add with intrinsics you are implementing here.

It looks  like it is only this one:

//BFMUL:
svbfloat16x2_t svmul[_bf16_x2](svbfloat16x2_t zd, svbfloat16x2_t zm) __arm_streaming;
svbfloat16x2_t svmul[_single_bf16_x2](svbfloat16x2_t zd, svbfloat16_t zm) __arm_streaming;
svbfloat16x4_t svmul[_bf16_x4](svbfloat16x4_t zd, svbfloat16x4_t zm) __arm_streaming;
svbfloat16x4_t svmul[_single_bf16_x4](svbfloat16x4_t zd, svbfloat16_t zm) __arm_streaming;
