coresight: etm: Make cycle count threshold user configurable

When cycle counting is enabled, we use a default threshold value i.e 0x100
for the instruction trace cycle counting.

This patch makes the cycle threshold user configurable via perf event
attributes( 'cc_threshold' => event->attr.config3[11:0] ), falling back
to the current default if unspecified.
