[PATCH] drm/amdgpu: reduce the full gpu access time in amdgpu_device_init.

[chong li <chongli2@amd.com>]

[Why]
function "devm_memremap_pages" in function "kgd2kfd_init_zone_device",
sometimes cost too much time.

[How]
move the function "kgd2kfd_init_zone_device" after release full gpu access(amdgpu_virt_release_full_gpu).
