EDAC/mce_amd: Print syndrome register value on SMCA systems
Print SyndV bit status and print the raw value of the MCA_SYND register.
Further decoding of the syndrome from struct mce.synd can be done in
other places where appropriate, e.g. DRAM ECC.
Boris: make the error stanza more compact by putting the error address
and syndrome on the same line:
[Hardware Error]: Corrected error, no action required.
[Hardware Error]: CPU:2 (17:0:0) MC4_STATUS[-|CE|-|PCC|AddrV|-|-|SyndV|CECC]: 0x96204100001e0117
[Hardware Error]: Error Addr: 0x000000007f4c52e3, Syndrome: 0x0000000000000000
[Hardware Error]: Invalid IP block specified.
[Hardware Error]: cache level: L3/GEN, tx: DATA, mem-tx: RD
