To support cases such as FW update or Core dump, the t7xx
device is capable of signaling the host that a special port
needs to be created before the handshake phase.
Adds the infrastructure required to create the early ports
which also requires a different configuration of CLDMA queues.
Base on the v5 patch version of follow series:
'net: wwan: t7xx: fw flashing & coredump support'
