[PATCH] drm/amd/pm: Enable smu v13_0_6 eccinfo in firmware query mode

[Zhang, Hawking]

[AMD Official Use Only - General]

Let' s see if we can retire the get_ecc_info callback since from smu_v13. (i.e., do not provide the callback implementation). What we just need to ensure the driver can fallback to direct poll mode when aca debug mode is enabled, this applies to both error query and bad page retirement.

Thoughts?

Regards,
Hawking
