Using libdrm to talk to the amdgpu driver.  It is not used for anything
critical at this point but it will be used to configure for things like
GPU hung detection, etc.

Using two different ways to obtain amdgpu firmware version as a way to
validate libdrm integration.  The same firmware version can be obtained
via debugfs from /sys/kernel/debug/dri/(card num)/amdgpu_firmware_info
or using amdgpu_query_firmware_version API from libdrm.
