Initially, those strings describing different parts of an MCE message
were shared with amd64_edac and were therefore exported to modules.
However, all except pp_msgs are used only in one place right now so hide
them and make them static.
No functionality change.

Add MCE decoding logic for AMD Family 16h processors.
Boris:
- drop unneeded uu_msgs export
- exit early in cat_mc1_mce and save us an indentation level

Currently only AMD Family 15h processors have special handling for MC2
errors. Since upcoming Family 16h will also need unique handling, let's
make MC2 handling part of amd_decoder_ops.

Having the functional unit names in each bank decode is only misleading
as this code supports multiple families and there's no guarantee the
mapping between FUs and MCE banks will stay the same.
And also, knowing the functional unit name doesn't help much since you
end up looking at the respective BKDG anyway.
So drop all FU references and use the MC bank numbers instead.

Needed for shifting 64-bit values on 32-bit, like MSR values,
for example.

Remove reporting of errors with UC bit set - this is done by the MCE
decoding code anyway and this driver deals with DRAM ECC errors only. UC
(NB uncorrectable error) doesn't necessarily mean it is a DRAM error.
Remove unused macros while at it.
