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.
