[PATCH 3/3 v2] MIPS: introduce CPU_R4K_CACHE_TLB

[PATCH 3/3 v2] MIPS: introduce CPU_R4K_CACHE_TLB

[Florian Fainelli]

R4K-style CPUs having common code to support their caches and tlb have this
boolean defined by default. Allows us to remove some lines in
arch/mips/mm/Makefile.

Changes since v1:
- removed CPU_XLR already covered by CPU_R4K_CACHE_TLB
- add back CPU_R8000 to Kconfig exception list and Makefile
