[PATCH] powerpc: Remove a few lines of oops output

[Anton Blanchard <anton@samba.org>]

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.

PACATMSCRATCH is a long and not very descriptive name. It appears to be
an MSR so should it instead be called TM_MSR?

Also, could we save a line and only print it if MSR_TM_ACTIVE()?
