Updates for the RMI MIPS platform code

Browse Source 
- set cache_coherent_dma flag in cpuinfo for XLR, this will make sure that
  BUS_DMA_COHERENT flag is handled correctly in busdma_machdep.c
- iodi.c, call device_get_name() just once
- clear RMI specific EIRR while intializing CPUs
- remove debug print in intr_machdep.c
