SGI IP28 machines would need special treatment (enable adding addtional
wait states) when accessing memory uncached. To avoid this pain I
changed the driver to use only cached access to memory.

Hi,
after chasing and fixing two jazz platform bugs and one MIPS dma mapping
bug, I finally succeeded in using the Dave's new esp_core (great work,
thank you Dave). Below is the patch.
Thomas.

Reason is that SGI IP27 always generates 64bit DMA addresses and has
no fallback mode for 32bit DMA addresses implemented. QLA1280
supports 64bit addressing for all DMA accesses so setting coherent mask
to 64bit fixes the issue.
