drm/amdgpu: disable DRAM memory training when GECC is enabled
GECC and G6 mem training are mutually exclusive
functionalities. VBIOS/PSP will set the flag
(BOOT_CFG_FEATURE_TWO_STAGE_DRAM_TRAINING) in
runtime database to indicate whether dram memory
training need to be disabled or not.
For Navi1x families, two stage mem training is always
enabled.
