Allocating larger buffers allows KMD/HW to enable optimizations that makes access to memory faster, also because of minimum alignment required in some cases we allocate 4k or 64k long buffers for usages that only needs a few bytes, wasting a lot of memory. Memory pool takes care of both of those things and here I'm adding the base infrastruture to implement this feature. The next patch will implement the functions in anv_slab_bo.c, spliting it in two to make review easier. The idea here is take the same approach as Iris and use pb_slab.h. In 99% of the places it will be transparent that anv_bo is actually a slab of a larger and real anv_bo, the remaning 1% of the places are handled here.
