[PATCH] drm/amdkfd: Add NAVI12 support from kfd side

[Liu, Shaoyun]

I will push to drm-next branch . After check the code again , this change will cause  issue in the  kfd since CHIP_NAVI12  not added  in other place where check the device_info->asic_family  in kfd code .  I think it's better just set the  family ID as CHIP_NAVI10  since there is no difference from the kfd side for NAVI10, NAVI12 and    NAVI14.  I will send  another review .


Regards
