Stephane Eranian d038b12c6d perf: Fix Pentium4 raw event validation
This patch fixes some issues with raw event validation on
Pentium 4 (Netburst) based processors.

As I was testing libpfm4 Netburst support, I ran into two
problems in the p4_validate_raw_event() function:

   - the shared field must be checked ONLY when HT is on
   - the binding to ESCR register was missing

The second item was causing raw events to not be encoded
correctly compared to generic PMU events.

With this patch, I can now pass Netburst events to libpfm4
examples and get meaningful results:

  $ task -e global_power_events🏃u  noploop 1
  noploop for 1 seconds
  3,206,304,898 global_power_events:running
