René Rebe 50c26c301c drm/ast: Swap framebuffer writes on big-endian machines ...

Swap the pixel data when writing to framebuffer memory on big-endian
machines. Fixes incorrect output. Aspeed graphics does not appear to
support big-endian framebuffers after AST2400, although the feature
has been documented.

There's a lengthy discussion at [1].

v5:
- avoid restricted cast from __be16 (kernel test robot)
