greybus: control: add bundle suspend and resume preparations
Add the AP implementation for the Greybus Control Bundle Suspend
Operation. This Operation is used to request a Bundle to enter the
BUNDLE_SUSPENDED state, all Connections associated with this Bundle must
be closed before issuing this operation.
Add the AP implementation for the Greybus Control Bundle Resume
Operation. This operation request a specific Bundle to transition from
the BUNDLE_SUSPENDED state to the BUNDLE_ACTIVE state.
