capsule: fwu: transition the platform state on a successful update

Browse Source 
Transition the platform to either Trial State or Regular State on a
successful update. Do this by calling the fwu_state_machine_updates()
API function.

For version 1 of the FWU metadata, the transition to Trial State is
done by starting the Trial State counter, while for version 2, in
addition to the counter, the bank_state field of the FWU metadata is
also updated to Valid.

For transitioning the platform to Regular State, no action is needed
with version 1 of the FWU metadata structure, while for version 2, the
bank_state field is set to Accepted.
