minigbm: More sophisticated gbm_bo_map/gbm_bo_unmap
We previously added the gbm_bo_map/gbm_bo_unmap (see CL:393927)
entry points since we wanted to do driver-specific detiling during
screenshot capture tests. We ignored most the parameters and mapped
the entire buffer. This CL adds the ability to:
1) Return the starting address within a byte given a specific x, y
in the buffer.
2) Handle the case where there are more than one kernel buffers
per buffer object. Currently, only the Exynos driver would use
this capability.
