drm/amd/ras: apply the MCA debug mode on every RAS resume

Browse source

amdgpu_ras_late_init() sends the MCA configuration to PMFW, but it runs
before RAS is ready on a device that still needs a hive reset, so the
request is dropped and CE polling stays disabled. A reset loses the
setting too, since PMFW is reloaded and nothing programs it again.

The request is a single SMU message and does not depend on the RAS block
being up, so amdgpu_ras_mgr_set_debug_mode() no longer requires it. Send
it from amdgpu_ras_resume(), which covers modprobe, resume from suspend,
GPU reset and reset on init, and drop it from amdgpu_ras_late_init().
