drm/amdgpu: add interface to get die id from memory address

And implement it for UMC v12_0. The die id is calculated from IPID
register in bad page retirement flow, but we don't store it on eeprom
and it can be also gotten from physical address.

v2: get PA_C4 and PA_R13 from MCA address since they may be cleared in
retired page.
