[PATCH v2 2/2] drm/amd/amdgpu/amdgpu_drv.c: Replace drm_modeset_*_all with DRM_MODESET_LOCK_ALL_*

[Fabio M. De Francesco]

Replace the deprecated API with new helpers, according to the TODO list
of the DRM subsystem. The new API has been introduced with commit
b7ea04d299c7: DRM_MODESET_LOCK_ALL_BEGIN() simplifies grabbing all modeset
locks using a local context and has the advantage of reducing boilerplate.
