extcon: Initialize blocking notifier while registering

Browse Source 
This change initializes the blocking notifier while registering
a new extcon device. Without this a warning is observed when
CONFIG_LOCKDEP is enabled since it is not as per lockdep
annotation, as the driver is trying to register a non-static key.
