Those get reported in MC0_STATUS, see Table 92, F10h BKDG (31116, rev.
3.28) for more details.

This is the MCE error code from the MCi_STATUS banks, bits [15:0] which
describe what type of error was encountered: GART TLB, Memory or Bus
error. The semantics of those bits are identical across all MCE banks so
decode those separately, irrespectively of MCE type.

The MCi_STATUS registers have most field definitions in common so decode
them in the general path. Do not pass ecc_type along and compute it in
__amd64_decode_bus_error instead.

Move NB decoder along with required defines to EDAC MCE core. Add
registration routines for further decoding of the MCE info in the AMD64
EDAC module.

This is in preparation of adding AMD-specific MCE decoding functionality
to the EDAC core. The error decoding macros originate from the AMD64
EDAC driver albeit in a simplified and cleaned up version here.
While at it, add macros to generate the error description strings and
use them in the error type decoders directly which removes a bunch of
code and makes the decoding functions much more readable. Also, fix
strings and shorten macro names.
Remove superfluous htlink_msgs.
