drm/amdgpu: add interface to get die id from memory address2024-12-10T15:26:47ZTao Zhou2024-10-30T08:42:42Zurn:sha1:fcb600b07894913a9e73d8c1a1ce86a36324e4a7
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.

v1 (legacy way): store channel index within a UMC instance in eeprom
v2: store global channel index in eeprom
V2: only save the flag on eeprom, clear it after saving.

Save the global channel index returned by RAS TA to eeprom.
We can get memory physical address by MCA address and channel index.
