powerpc/powernv/mce: Reduce MCE console logs to lesser lines.
Also add cpu number while displaying MCE log. This will help cleaner
logs when MCE hits on multiple cpus simultaneously.
Before the changes the MCE output was:
Severe Machine check interrupt [Recovered]
NIP [d00000000ba80280]: insert_slb_entry.constprop.0+0x278/0x2c0 [mcetest_slb]
Initiator: CPU
Error type: SLB [Multihit]
Effective address: d00000000ba80280
After this patch series changes the MCE output will be:
MCE: CPU80: machine check (Warning) Host SLB Multihit [Recovered]
MCE: CPU80: NIP: [d00000000b550280] insert_slb_entry.constprop.0+0x278/0x2c0 [mcetest_slb]
MCE: CPU80: Probable software error (some chance of hardware cause)
UE in host application:

and for MCE in Guest:
