[PATCH] ppc32: Fix a problem with NTP on !(chrp||gemini)

The following problem was found by Giovambattista Pulcini
<gpulcini@swintel.it>, who also provided a partial patch, and this has been
verified by our time guru Gabriel Paubert <paubert@iram.es>.

The problem is that in do_settimeofday() we always set time_state to
TIME_ERROR and except on two platforms, never re-set it.  This meant that
ntp_gettime() and ntp_adjtime() always returned TIME_ERROR, incorrectly. 
Based on Gabriel's analysis, time_state is used for leap-second processing,
and ppc shouldn't be mucking with it.
