[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) Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
