If we call flush_cache(0xfffff000, 0x1000) it would never
terminate the loop since end = 0xffffffff and we'd roll over
our counter from 0xfffffe0 to 0 (assuming a 32-byte cache line)

- It is possible to miss flush/invalidate the last
cache line, we fix it at here.
- add the volatile and memory clobber.

Some boards (e.g. lwmon5) need rather a frequent watch-dog
kicking. Since the time it takes for the flush_cache() function
to complete its job depends on the size of data being flushed, one
may encounter watch-dog resets on such boards when, for example,
download big files over ethernet.
