drm/amdgpu: Decouple RAS EEPROM addresses from chips 

Abstract RAS I2C EEPROM addresses from chip names, and set their macro
definition names to the address they set, not the chip they attach
to. Since most chips either use I2C EEPROM address 0 or 40000h for the RAS
table start offset, this leaves us with only two macro definitions as
opposed to five, and removes the redundancy of four.
