[PATCH 00/13] Bus cleanup infrastructure and fixes

[David Marchand]

This is a followup of the previous bus refactoring.
See https://inbox.dpdk.org/dev/CAJFAV8zvFpLwz8SY8DUUezyJyM43eRZ17Yj30ex808eHC4ZE=g@mail.gmail.com/.

This series refactors the bus cleanup infrastructure to reduce code
duplication and fix resource leaks in several bus drivers.
It should address the leak Thomas pointed at.

The first part of the series (patches 1-8) addresses several bugs and
inconsistencies:
- Documentation and log message inconsistencies from earlier bus
  refactoring
- Device list management issues in dma/idxd and bus/vdev
- Resource leaks in PCI and VMBUS bus cleanup (mappings and interrupts)
- Simplified device freeing in NXP buses (DPAA and FSLMC)
- Deferred interrupt allocation to probe time (NXP buses, VMBUS)

The core infrastructure changes (patches 9-10) introduce the generic
cleanup framework:
- Refactors unplug operations to be the counterpart of probe_device
- Implements rte_bus_generic_cleanup() to centralize cleanup logic
- Adds .free_device operation to struct rte_bus
- Adds compile-time verification that rte_device is at offset 0

The final patches (11-13) convert remaining buses to use the generic
cleanup helper:
- DPAA bus: add unplug support
- VMBUS bus: switch to embedded device name and add unplug support

After this series, most buses use the generic cleanup helper, eliminating
duplicated code and ensuring consistent cleanup behavior across the
codebase.
