[PATCH 07/11] drm/amdgpu/gfx6: Properly enable/disable priv_req and priv_inst interrupts

["Timur Kristóf" <timur.kristof@gmail.com>]

These were used without ever calling get()/put() on them.
Implement it like on GFX7-8:

* Call amdgpu_irq_get() from gfx_v6_0_late_init()
* Call amdgpu_irq_put() from gfx_v6_0_hw_fini()
