[PATCH] Revert "drm/amd/amdgpu: Fix potential ioremap() memory leaks in amdgpu_device_init()"

[Ma Jun]

This patch causes the following iounmap erorr and calltrace
iounmap: bad address 00000000d0b3631f

So just revert it and amdgpu_device_fini_sw() will cleanup the
rmmio mapping.

This reverts commit 923f7a82d2e12a99744a940954f3829ab18a9dc7.
