From 35f894ab4986da2cec7bf323b3f815738cfd0e2c Mon Sep 17 00:00:00 2001

Subject: Add initfiles for trace default setup

 - Stop trace on xstop+recov for core, cache, nest
 - Stop trace on xstop for all other chiplets
 - Synchronous start/stop of nest trace via N3
 - Set up fabric compression mask so we're not swamped with bogus entries
 - Set up PIB trace compression to only look for valid bit
