MIPS: Remove unused R8000 CPU support

Browse Source 
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
suitable Linux distribution to support this.
