Mike Leach 42b2b570b3 perf cs-etm: Update ETM metadata format 
The current fixed metadata version format (version 0), means that adding
metadata parameter items renders files from a previous version of perf
unreadable. Per CPU parameters appear in a fixed order, but there is no
field to indicate the number of ETM parameters per CPU.

This patch updates the per CPU parameter blocks to include a NR_PARAMs
value which indicates the number of parameters in the block.

The header version is incremented to 1. Fixed ordering is retained,
new ETM parameters are added to the end of the list.

The reader code is updated to be able to read current version 0 files,
For version 1, the reader will read the number of parameters in the
per CPU block. This allows the reader to process older or newer files
that may have different numbers of parameters than in use at the
time perf was built.
