David Gibson b06e55c88b Prevent crash on modulo by zero 
1937095 "Prevent crash on division by zero" fixed a crash when attempting
a division by zero using the / operator in a dts.  However, it missed the
precisely equivalent crash with the % (modulus) operator.  This patch fixes
the oversight.

David Gibson 1937095588 Prevent crash on division by zero 
Currently, attempting to divide by zero in an integer expression in a dts
file will cause dtc to crash with a division by zero (SIGFPE).

This patch corrects this to properly detect this case and raise an error.
