PASR: mm: Integrate PASR in Buddy allocator

Any allocators might call the PASR Framework for DDR power savings. Currently,
only Linux Buddy allocator is patched, but HWMEM and PMEM physically
contiguous memory allocators will follow.

Linux Buddy allocator porting uses Buddy specificities to reduce the overhead
induced by the PASR Framework counter updates. Indeed, the PASR Framework is
called only when MAX_ORDER (4MB page blocs by default) buddies are
inserted/removed from the free lists.

To port PASR FW into a new allocator:

* Call pasr_put(phys_addr, size) each time a memory chunk becomes unused.
* Call pasr_get(phys_addr, size) each time a memory chunk becomes used.
