    [MIPS] SNI RM updates
    
    - use RTC_CLASS instead of GEN_RTC
    - get rid of ds1216 in favour of a RTC_CLASS driver
    - use correct console device for older RM400
    - use physical addresses for 82596 device
    - use 128 byte L1 cache line size (this is needed because most of the
      SNI caches are using 128 L2 cache lines)
