Revert "drm/amd/amdgpu: Fix potential ioremap() memory leaks in amdgpu_device_init()"
This patch causes the following iounmap erorr and calltrace
iounmap: bad address 00000000d0b3631f
The original patch was unjustified because amdgpu_device_fini_sw() will
always cleanup the rmmio mapping.
This reverts commit eb4f139888f636614dab3bcce97ff61cefc4b3a7.
