ec/google/chromeec: Add library function google_chromeec_events_init

mainboard_ec_init implemented by all x86-based mainboards using
chromeec performed similar tasks for initializing and recording ec
events. Instead of duplicating this code across multiple boards,
provide a library function google_chromeec_events_init that can be
called by mainboard with appropriate inputs to perform the required
actions.

This change also adds a new structure google_chromeec_event_info to
allow mainboards to provide information required by the library
function to handle different event masks.

Also, google_chromeec_log_device_events and google_chromeec_log_events
no longer need to be exported.
