> Move common device bring-up and teardown into mana_gd_setup() and

> enumeration, interrupt-pool sizing, and servicing workqueue management.
> Record the vPort count for transport-specific queue sizing and keep shared
> IRQ context bookkeeping in the core.

> This prepares the driver for additional bus transports without duplicating
