ip32 kconfig patch

IP32 needs the below to build CVS. rm7k_sc_enable and __rm7k_sc_enable in arch/mips/mm/sc-r7k.c reference the MIPS32 KSEG{0,1}ADDR macros. I dont know enough about MIPS to fixup the KSEGxADDR references unfortunately, but this lets me build for R10k at least.

Resulting kernel didnt /seem/ to boot though on an R12k O2 - I cant tell for sure sadly, no console at all, but it didnt blink the keyboard leds - and not sure if thats related.. i think r10k and r12k use the r4k cache enable functions, anyone know?.
