EDAC/mce_amd: Decode MCA_STATUS in bit definition order
Sort the MCA_STATUS bits in decode output to follow how they are defined
in the register.
The order is as follows:
Bit | Decode
------------
62 | Over
61 | UC
59 | MiscV
58 | AddrV
57 | PCC
55 | TCC
53 | SyndV
46 | CECC
45 | UECC
44 | Deferred
43 | Poison
40 | Scrub
[ bp: Massage a bit. ]
