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. BUG=None TEST=Ran with cache_test code (see separate CL) and closely examined the resulting output. Made sure results look as expected (iterating through all sets (inner) and ways (outer) for L1 and then L2 cache, extracting the right numbers from CLIDR and CCSIDR, not touching anything twice). Time for a single dcache_clean_invalidate_all() on Nyan drops from 3.7ms to 0.3ms.
