DreamLite-base fails to load due to unsupported legacy UNet block type names

[ElectricGoal]

DreamLitePipeline.from_pretrained("carlofkl/DreamLite-base") currently fails while constructing the UNet because the saved config uses legacy/upstream-style block type names that DreamLiteUNetModel does not accept.

Minimal repro:

from diffusers import DreamLitePipeline

pipe = DreamLitePipeline.from_pretrained(
  "carlofkl/DreamLite-base", torch_dtype=torch.bfloat16
).to("cuda")

Observed error includes:

ValueError: DreamLite does not support down_block_type='CrossAttnDown*' and up_block_type='CrossAttnUp*'
