amd64_edac: Modify usage of amd64_read_dct_pci_cfg()
Rationale behind this change:
- F2x1xx addresses were stopped from being mapped explicitly to DCT1
from F15h (OR) onwards. They use _dct[0:1] mechanism to access the
registers. So we should move away from using address ranges to select
DCT for these families.
- On newer processors, the address ranges used to indicate DCT1 (0x140,
0x1a0) have different meanings than what is assumed currently.
Changes introduced:
- amd64_read_dct_pci_cfg() now takes in dct value and uses it for
'selecting the dct'
- Update usage of the function. Keep in mind that different families
have specific handling requirements
- Remove [k8|f10]_read_dct_pci_cfg() as they don't do much different
from amd64_read_pci_cfg()
- Move the k8 specific check to amd64_read_pci_cfg
- Remove f15_read_dct_pci_cfg() and move logic to amd64_read_dct_pci_cfg()
- Remove now needless .read_dct_pci_cfg
Testing:
- Tested on Fam 10h; Fam15h Models: 00h, 30h; Fam16h using 'EDAC_DEBUG'
and mce_amd_inj
- driver obtains info from F2x registers and caches it in pvt
structures correctly
- ECC decoding works fine
