[U-Boot-Users] [id]cache_status looks at wrong bit for MPC8560

If they are wrong on 8560 they are wrong on 85xx since the same code  
is used for all 85xx.

However, looking at the code my guess is that [id]cache_status return  
0 if the caches are off and any non-zero value if they are on.  So  
from that point of view the code appears to be ok.  When you say they  
are looking at the wrong bit, what exactly do you mean?
