perf/x86/intel/pt: Factor out pt_config_enable()
pt_config() enables tracing by allowing NMIs and pause/resume, issuing
the necessary barriers, and calling pt_config_start(). A later change
needs to re-enable tracing on a (re-)start path without repeating the
full pt_config() setup (filters, RTIT_CTL, buffer configuration).
Factor that enabling sequence out into a new helper, pt_config_enable(),
so it can be called on its own.
No functional change intended.
