I removed outer loops in ...wait_msgint_ready the sleeptime and
retrycount are in fact never changed so I changed them into
defines. In arcmsr_flush_hba_cache is a loop removed, which printed
the same printk 100 times, one line in log is enough I think.  The
arcmsr_sleep_for_bus_reset has lost a functionality with the latest
patches, The only thing the function does is a long sleep, so it's
replaced with a ssleep.
