simd_norm input parameters update

[zehonyi21]

current input parameters for simd_norm are not consistent with those of 'torch.norm'(refer to https://docs.pytorch.org/docs/stable/generated/torch.norm.html) thus I changed it accordingly * note that my pytorch does not require 'out' as input paramters so I didn't add it (return torch.norm(self, p, dim, keepdim, dtype=dtype))
