WIP: lima: fix mipmapping for linear textures

Mali4x0 has stride only for level 0, so other leves have stride of width * bpp. That likely means that any level except 0 can't be render target. We can workaround it by using tiled textures wherever possible since they're actually aligned to tile boundaries.
