[Feature] AMD Nitro-E Support

[JohnLoveJoy]

Feature Summary

New compact model with Efficient Multimodal Diffusion Transformer (E-MMDiT)

Detailed Description

AMD presented a very promising super faster model for those with limited resources like smartphones and iGPUs, I wonder how this will scale with more parameters or paired with controlNet.
