[PATCH 13/21] drm/amdgpu: support to find RAS bad pages via old TA

[Tao Zhou]

Old version of RAS TA doesn't support to convert MCA address stored on
eeprom to physical address (PA), support to find all bad pages in one memory
row by PA with old RAS TA. This approach is only suitable for nps1 mode.
