Subject: [PATCH v3 0/4] ACPI: platform: Fix SMB0001 enumeration on Kontron devices

After switching i2c-scmi driver to be a plaform one, it stopped
being enumerated on number of Kontron platforms, because it's
listed in the forbidden_id_list.

To resolve the situation, add a flag and count the resources of the
forbiden device. If the count is non-zero, the device must be skipped.

Changelog v3:
- provided completely rewritten solution (Rafael)
- due to above, added two new patches
- due to above, dropped tags from patch 3

Andy Shevchenko (4):
  ACPI: bus: Constify acpi_companion_match() returned value
  ACPI: bus: Introduce acpi_match_acpi_device() helper
  ACPI: platform: Ignore SMB0001 only when it has resources
  ACPI: platform: Move SMB0001 HID to the header and reuse
