Turns out that when you clear 28 bits starting with bit 3, you leave bit
31 standing. Ooops...
This shouldn't really matter since that bit is reserved/SBZ in CLIDR
anyway, but it's still nice to fix it. This whole thing should really be
an AND for clarity anyway in my opinion.
Bug found in upstream NetBSD (who would've thought...).
BUG=None
TEST=Still boots.

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.
