gpu: nvgpu: Support multiple types of allocators
Support multiple types of allocation backends. Currently there is
only one allocator implementation available: a buddy allocator.
Buddy allocators have certain limitations though. For one the
allocator requires metadata to be allocated from the kernel's
system memory. This causes a given buddy allocation to potentially
sleep on a kmalloc() call.
This patch has been created so that a new backend can be created
which will avoid any dynamic system memory management routines
from being called.
