[PATCH v3 03/13] devtools: support Intel drivers in doc check

[David Marchand <david.marchand@redhat.com>]

Intel network drivers are located in a subdirectory
(drivers/net/intel/) rather than directly in drivers/net/.

Update all_net_drivers() to find drivers based on meson.build
presence, which handles both locations.

Add driver_code_dir() helper to map driver names to their actual
code directory.

Update changed_net_drivers() to extract driver names from Intel
subdirectory paths.

Changes since v2:
- split changes out of original patch 3, now only dealing with Intel sub
  directory case,
