NCI2.0: Add init and core reset functionality for NCI 2.0

The commands for CORE_INIT and CORE_RESET have changed. The stack will
try and initialize the NFCC assuming it supports NCI 2.0, if in case the
responses aren't as per specification, it will try with NCI 1.0
commands.

Test: Enabling sequence with NCI 2.0 works.
