Introduce optimized iomemcpy function for copying from io memory.

Reading from IO memory (pci rom or flash) is very slow, so add
   iomemcpy() which will yield during copy.  Use a 4 byte copy to
   optimize accesses.
Also, decompress cbfs data files from a temp memory buffer so that
   ulzma doesn't read from slow IO memory.
