ARM: Partially revert "Auto calculate ZRELADDR and provide option for exceptions" 



Partially revert e69edc79, which introduced automatic zreladdr
support.  The change in the way the manual definition is defined
seems to be error and conflict prone.  Go back to the original way
we were handling this for the time being, while keeping the automatic
zreladdr facility.
