Modified Files:
        src/sys/dev/ic: siisata.c

Log Message:
Correct various siisata bugs, some old, some new.

 - Move clearing of interrupts to before atastart() is called in the
   xfer interrupt handler.  Should fix kern/41579.
 - Using cv_timedwait(9) is not possible in code that can be called from
   interrupt context, fall back to DELAY(9).
 - Correctly poll Port Slot Status register for soft reset PRBs.
 - Only use the Recive Transfer Count register on reads, when it is valid.
 - Activate PRBs in a way that takes the whole physical address into account,
   even when the PRB is beyond 4GiB.
 - consistently use DELAY(9)
 - Use DELAY() constants in completion polling loops that are consistent with
   the loop count limit. (i.e. timeout in 10 rather than 100 seconds)
