net: mana: Introduce gdma_bus_ops for bus-specific operations

Browse source

Introduce per-device gdma_bus_ops for interrupt allocation, IRQ lookup,
reset, servicing, and bus-specific capabilities. Route the shared GDMA
code through these callbacks and provide the PCI implementation.

Move common device bring-up and teardown into mana_gd_setup() and
mana_gd_cleanup(), including hardware-channel initialization, device
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
the core or adding configuration checks throughout it.
