drm/suballoc: Extract amdgpu_sa.c as generic suballocation helper
Suballocating a buffer object is something that is not driver-specific
and useful for many drivers.
Use a slightly modified version of amdgpu_sa.c
v2:
- Style cleanups.
- Added / Modified documentation.
- Use u64 for the sizes and offset. The code dates back to 2012 and
using unsigned int will probably soon come back to bite us.
We can consider size_t as well for better 32-bit efficiency.
- Add and document gfp, intr and align arguments to drm_suballoc_new().
- Use drm_printer for debug output.
v3:
- Remove stale author info (Christian König)
v4:
- Avoid 64-bit integer divisions (kernel test robot <lkp@intel.com>)
- Use size_t rather than u64 for the managed range. (Thomas)
