arch: armv7: Fix cache sync instructions.
When the i-cache is on and the d-cache is off, the L1 i-cache is still
fetching information through L2 cache.
Since L2 cache is never invalidated, it has stale information.
BRANCH=storm
BUG=none
TEST=Resolves the invalidate data fetch from i-cache while jumping from
bootblock to romstage.
