[v3] Fix definitions for dbcr0, dbcr1, & dbcr2 register for bookE processors

Updates: Made names match BookeE names in BookeE spec, Added comment that DBCR0_RST* was not followed in fsl.
         * Did not get a chance to add missing entries for other cases with DBCR1 & DBCR0 .. but if anyone
           would like to add them, that would be awsome!

Taken from the PowerPC ISA BookIII-E specifies that DBCR0 is different  for all others that are not ppc405 chips. So I have now chnaged the conditional to reflect this. Also added definitions needed for DBCR1 & DBCR2.
