ARM: CPU: arm926ejs: Consolidate cache routines to common file
Four different boards had different options for enabling cache
that were virtually all the same. This consolidates these
common functions into arch/arm/cpu/arm926ejs/cache.c
This also has the positive side-effect of enabling cache on
the Davinci (da850) boards.
