arm: Fix up new cache flush algorithm and replace dcache_*_all() with it

This patch fixes the remaining few bugs in our shiny new cache iteration
    by set/way/level algorithm to actually make it work: It makes it start
    from cache level 0 (previously it would always start at LoC and be
    "done" instantly), fixes up the two shifts that isolate the set bits at
    the end (which didn't seem to account for the fact that the first shift
    affects the second), and throws an S bit on that last shift so that it
    actually affects the conditionals after it.

In addition, also moves the next_level block to the top so that we can
    share (and thus eliminate) some code at initialization, and turns the
    whole thing into a thrice-instantiated macro to create functions that
    fit our existing interface.
