arch/mips: provide proper cache primitives

This provides the opportunity to remove the kludge of disabling caches
altogether in the bootblock.

[pg: originally, this commit also provided automatic cache management
after loading stages, ie. flush dcache, so code ends up in icache. This
is done differently in upstream, so it's left out here]

BUG=chrome-os-partner:34127, chrome-os-partner:31438
TEST=with this fix romstage, ramstage and payload are executed properly
BRANCH=none
