[PATCH 01/10] ARM: cache: restore cache functions from the PBL

[Andre Heider]

When using CONFIG_MMU_EARLY combined with CONFIG_PBL_IMAGE, the barebox
setup reuses the MMU setup from the PBL, but doesn't setup the cache
functions.

Set these up to guarantee proper early cache handing before mmu_initcall().
