lib/intel_bufops: Introduce buffer operations
Different GENs supports different tile surfaces. Older GENs
have HW fences to allow X / Y surface tiling / detiling.
Newer GENs have to tile / detile such surface in software.
To make test developer life easier this code adds buffer
operations (short buf_ops) to use appropriate functions allowing
copying linear buffer to BO and from BO to linear buffer
regardless GPU generation and tiling/swizzling within BO. For GENs
having fences support preference is to use them if they are available
(X / Y tiling is probed on buf_ops initialization).
Note: on Gen2 code supports only HW tiling at the moment.
