Move ops which don't support FP16 dtype to FP32 list

[anirudh2290]

Description

Some legacy ops call this InferType function here: https://github.com/apache/incubator-mxnet/blob/master/include/mxnet/operator.h#L228 ,which doesnt support FP16 dtype. Tweaking the AMP lists so that users don't run into issues like the one mentioned here: https://discuss.mxnet.io/t/convert-model-to-float16/5053/3

@ptrendx can you please take a look.

LGTM. Why did you remove the BN v1 and Polling v1? Do they support fp16?

it was a mistake. removed it now. yes they do support FP16, they have their own InferType functions.
