HWMEM: Break out allocator
Break out allocator in order to be able to run it in multiple instances
ie support multiple regions. Multiple regions can be used to battle
fragmentation by letting clients allocating in a non fragmenting way
allocate from their own region. For STE this will probably mean letting
camera/video have their own region. A positive side effect is that we
can use HWMEM as an allocator for SRAM if we want to.
