drm/amdgpu: validate bad page threshold in ras(v3)
Bad page threshold value should be valid in the range between -1 and max records length of eeprom. It could determine when saved bad pages exceed threshold value, and proceed corresponding actions. v2: When using the default typical value, it should be min value between typical value and eeprom max records length. v3: drop the case of setting bad_page_cnt_threshold to be 0xFFFFFFFF, as it confuses user.
