configs: Do not assume bootmem is a System child
As far as I can see bootmem is used in Arm systems only.
With
https://gem5-review.googlesource.com/c/public/gem5/+/21604
bootmem has been moved from system to system.realview.
This patch fix things by removing the assumption that the bootmem
SimObject lives under the system.
It is now trying to getattr a reference of the bootmem.
It is the ISA specific system builder's duty to bind the bootmem
reference (_bootmem) to the real bootmem object
