Control Port implements driver control messages such as modem-host
handshaking, controls port enumeration, and handles exception messages.
The handshaking process between the driver and the modem happens during
the init sequence. The process involves the exchange of a list of
supported runtime features to make sure that modem and host are ready
to provide proper feature lists including port enumeration. Further
features can be enabled and controlled in this handshaking process.

Registers the t7xx device driver with the kernel. Setup all the core
components: PCIe layer, Modem Host Cross Core Interface (MHCCIF),
modem control operations, modem state machine, and build
infrastructure.
* PCIe layer code implements driver probe and removal.
* MHCCIF provides interrupt channels to communicate events
such as handshake, PM and port enumeration.
* Modem control implements the entry point for modem init,
reset and exit.
* The modem status monitor is a state machine used by modem control
to complete initialization and stop. It is used also to propagate
exception events reported by other components.
