[ARM] 2892/1: remove gcc workaround for direct access to absolute memory addresses

Patch from Nicolas Pitre

It used to make a difference in the gcc-2.95 era.  However these days
modern gcc apparently got better at not being influenced by such constructs
(which is good in general) and therefore such workaround is of no real
advantage anymore.
The good news is that gcc (from version 4.1.0) is now fixed with
regards to the defficiency this workaround was trying to address.
For those interested the patch can easily be backported to older gcc
versions and can be found here:
