Add license identifier to files which Arm owns the copyright to,
and contain either BSD-3 or Apache-2.0 licenses. This is to address
license errors raised by scancode analysis.
In this commit, the analogin_s structure is moved to commonn_objects.h file
to limit the duplicaion.
The ADC handle is moved from a global variable to a struct member of the
analogin object. This allows multiple ADC instances to work correctly.
Note that State needs to be explicitely set to HAL_ADC_STATE_RESET
because the object is not zero initialized.
