Add some platform KOBJ extensions and continue integrating PowerPC

hypervisor infrastructure support:
- Fix coexistence of multiple platform modules in the same kernel
- Allow platform modules to provide an SMP topology
- PowerPC hypervisors limit the amount of memory accessible in real mode.
  Allow the platform modules to specify the maximum real-mode address,
  and modify the bits of the kernel that need to allocate
  real-mode-accessible buffers to respect this limits.
