Artyom Tarasenko 172e7644f3 target/sparc: fake UltraSPARC T1 PCR and PIC registers
Fake access to
   PCR Performance Control Register
and
   PIC Performance Instrumentation Counter.

Ignore writes in privileged mode, and return 0 on reads.

This allows booting Tribblix, MilaX and v9os under Niagara target.
