hw/arm: Fix Integrator/CM initialization

Browse Source 
Initialization of a class instance cannot depend on its own properties
as these are not yet set.  Move parts of integratorcm_init() that depend
on the "memsz" property to the newly added integratorcm_realize().

This fixes: https://bugs.launchpad.net/qemu/+bug/1624726
