drm/amd: Remove old radeon_sa funcs from kfd-->kgd interface

/**

 * struct kfd2kgd_calls

 *

 * @init_sa_manager: Initialize an instance of the sa manager, used by

 * amdkfd for all system memory allocations that are mapped to the GART

 * address space

 *

 * @fini_sa_manager: Releases all memory allocations for amdkfd that are

 * handled by kgd sa manager

 *

 * @allocate_mem: Allocate a buffer from amdkfd's sa manager. The buffer can

 * be used for mqds, hpds, kernel queue, fence and runlists

 *

 * @free_mem: Frees a buffer that was allocated by amdkfd's sa manager

 *

 * @init_gtt_mem_allocation: Allocate a buffer on the gart aperture.

 * The buffer can be used for mqds, hpds, kernel queue, fence and runlists
