It is unclear why max-memory-bandwidth should be set for CLCD on the
fast model. Removing that property allows allocating and using 32bpp
buffers, which may be desirable on certain platforms such as
Android.

Changes in v2:
- Remove the attribute completely instead of increasing its value. It is
optional and there is no clear reason why it should be set at all.
