[PATCH v2 00/16] Device unplug and bus cleanup refactoring for NXP

[David Marchand]

Hello Hemant,

This is a followup to the refactoring started in 26.07.

Like the last time, only compilation has been checked.
I have no hardware to test runtime.

One thing that could be broken is either the order of devices
initialisation, or bugs in the device filtering that I tried to
simplify.

I went with the approach of splitting the device list between
internal bus object (that I called "control" devices, maybe a better
name can be found), and normal bus device object for which DPDK has a
driver.

I did not get much feedback on the series.
I'll let CI pass on this new revision and merge it.

Changes since v1:
- rebased,
- used fd_close API,
- branch rebased against next-net is available here:
  https://github.com/david-marchand/dpdk/commits/dpaa_bus_next-net

Changes since RFC v2:
- rebased,
- fixed interrupt closing,

Changes since RFC v1:
- fixed FD leak in bus/dpaa pre existing code,
- fixed device name leak in bus/fslmc pre existing code,
- fixed other leaks found by AI review,
- split DPAA2 devices in two list:
  - one list in the bus object for devices for which a driver exists,
  - one list local to the fslmc bus code for internal resources that
    are initialised out of the EAL / bus framework,
