[PATCH] powerpc: remove support for bootmem-allocated memory for the DIU driver

[Timur Tabi]

Early versions of the Freescale DIU framebuffer driver depended on a bootmem
allocation of memory for the video buffer.  The need for this feature was
removed in commit 6b51d51a, so now we can remove the platform-specific code
that allocated that memory.

This patch is for 2.6.28.
