    powerpc: Remove a few lines of oops output
    
    We waste quite a few lines in our oops output:
    
    ...
    MSR: 8000000000009032 <SF,EE,ME,IR,DR,RI>  CR: 28044024  XER: 00000000
    SOFTE: 0
    CFAR: 0000000000009088
    DAR: 000000000000001c, DSISR: 40000000
    
    GPR00: c0000000000c74f0 c00000037cc1b010 c000000000d2bb30 0000000000000000
    ...
    
    We can do a better job here and remove 3 lines:
    
    MSR: 8000000000009032 <SF,EE,ME,IR,DR,RI>  CR: 28044024  XER: 00000000
    CFAR: 0000000000009088 DAR: 0000000000000010, DSISR: 40000000 SOFTE: 1
    GPR00: c0000000000e3d10 c00000037cc2fda0 c000000000d2c3a8 0000000000000001
    
    Also move PACATMSCRATCH up, it doesn't really belong in the stack
    trace section.
