MIPS: Remove unused R8000 CPU support
Our R8000 CPU support can only be included if a system selects
CONFIG_SYS_HAS_CPU_R8000. No system does, making all R8000-related CPU
support dead code. Remove it.

Using 8kB page size will result in higher performance kernel at
the price of higher memory consumption. This option is available
- only on R8000 and cnMIPS processors. Note that you will need a
