On chips without PowerPlay, pp_handle points to a struct amdgpu_device. The
resulting attempt to kfree() fields of the wrong struct ends in fire:

handle different firmware loading method. Since Vega10, there are
three ways to load firmware. It would be better to use a flag and a
fw_load_type kernel parameter to configure it.
