[PATCH v4 00/14] Modernization and fixes for NuBus subsystem

[Finn Thain <fthain@telegraphics.com.au>]

This series begins with cleanups and fixes for the NuBus subsystem and
finishes with a patch to add support for the Linux Driver Model.
A separate series (which requires this one) modernizes NuBus drivers.

Changes since v1:
- Added the missing NULL check in nubus_device_remove().
- Squashed the two /proc/bus/nubus/s/ patches into one patch.
- Combined the two sets of /proc/bus/nubus file operations into one set.
- Used the name 'nubus_rsrc' instead of 'nubus_functional_resource'.
- Used the name 'nubus_device_register' instead of 'nubus_device_add'.
- Dropped the unused EXPORT_SYMBOL(nubus_seq_write_rsrc_mem).
- Replaced licensing text in the new file with SPDX-License-Identifier.

Changes since v2:
- Implemented an idiomatic device release function for nubus boards.
- Removed the global nubus_boards linked list.
- Removed nubus_board pointer from proc dir entry private data to improve
  modularity.
- Adopted the standard linked list implementation.
- Disambiguated unrecognized and empty resources under /proc/bus/nubus.
- Reduced redundancy in proc dir entry private data to save some memory.
- Replaced /proc/nubus custom seq file ops with single_open().

Changes since v3:
- Added Acked-by and Reviewed-by tags.
- Moved the SPDX tag in bus.c to the first line of the file.
