Tzung-Bi Shih 525cb7ba66 platform/chrome: cros_ec_typec: Init mutex in Thunderbolt registration 
cros_typec_register_thunderbolt() missed initializing the `adata->lock`
mutex.  This leads to a NULL dereference when the mutex is later
acquired (e.g. in cros_typec_altmode_work()).

Initialize the mutex in cros_typec_register_thunderbolt() to fix the
issue.
