[PATCH, rs6000] correct an erroneous blip in the BU_P10_MISC define

Hi, 
    We have extraneous BTM entry (RS6000_BTM_POWERPC64) in the define for
our P10 MISC 2 builtin definition.  This does not exist for the '0',
'1' or '3' definitions. It appears to me that this was erroneously
copied from the P7 version of the define which contains a version of the
BU macro both with and without that element.  Removing the
RS6000_BTM_POWERPC64 portion of the define does not introduce any obvious
failures, I believe this extra line can be safely removed.

OK for trunk?

Thanks
