b0d3dc1291 Blackfin: bf526: restrict reboot workaround to 0.0 silicon 
The bug in the BF526 rom when doing a software reset exists only in older
silicon versions, so don't clear SWRST on newer parts.

803103925b Blackfin: use on-chip reset func with newer parts 
Turns out the documentation is wrong and doing "RAISE 1" does not result
in a software reset, only a core reset.  So when the on-chip rom has a
functioning reset helper, use it.
