Blackfin: reset watchdog in udelay()
All arches apparently should reset the watchdog in their udelay loop as
noted on the mailing list recently:
> A comment in flash_status_check() suggests that udelay() is
> expected to reset the watchdog, but I can't find any architecture
> where it does.
If this is missing in other architectures, it should be fixed at the
root cause, i. e. in udelay() or in the respective support routines.
