Revert "drm/amdgpu: fix aperture mapping leak"

In the Linux kernel, the following vulnerability has been resolved:

Revert "drm/amdgpu: fix aperture mapping leak"

devres teardown is LIFO. The aperture devres node was registered after
the DRM device node, so devres_release_all() unmaps the aperture before
the DRM device release callback fires amdgpu_device_fini_sw(). IP
sw_fini callbacks (e.g. vcn_v4_0_sw_fini) write to fw_shared through a
pointer derived from aper_base_kaddr, causing a kernel page fault on
probe failure / rollback:

  BUG: unable to handle page fault ... PMD 0
  RIP: vcn_v4_0_sw_fini+0x7b/0x170 [amdgpu]
  Call Trace:
    amdgpu_device_fini_sw
    amdgpu_driver_release_kms
    devm_drm_dev_init_release
    devres_release_all

This reverts commit d871e99879cb5fd1fa798b006b4888887e63a17a.
