powerpc: Make instruction dump work with scripts/decodecode
Matt reported that scripts/decodecode doesn't work for the instruction
dump in the powerpc oops output. Although there are scripts around that
can decode it, it would be preferable if the standard in-tree script
worked.
All other arches prefix the instruction dump with "Code:", and that's
what the script looks for, so use that.
The script then works as expected:
$ CROSS_COMPILE=powerpc64le-linux-gnu- ./scripts/decodecode
Code:
fbc1fff0 f821ffc1 7c7d1b78 7c9c2378 ebc30028 7fdff378 48000018 60000000

4: c1 ff 21 f8 stdu r1,-64(r1)
8: 78 1b 7d 7c mr r29,r3
...
Note that the script doesn't cope well with printk timestamps or printk
caller info.
