ACPI fixes for 5.17-rc5

- Change the log level of the "table not found" message in
    acpi_table_parse_entries_array() to debug to prevent it from
    showing up in the logs unnecessarily (Dan Williams).
 
  - Add a C-state limit quirk for 32-bit ThinkPad T40 to prevent it
    from crashing on boot after recent changes in the ACPI processor
    driver (Woody Suwalski).

Pull ACPI fixes from Rafael Wysocki:
 "These make an excess warning message go away and fix a recently
  introduced boot failure on a vintage machine.

  Specifics:

   - Change the log level of the "table not found" message in
     acpi_table_parse_entries_array() to debug to prevent it from
     showing up in the logs unnecessarily (Dan Williams)

   - Add a C-state limit quirk for 32-bit ThinkPad T40 to prevent it
     from crashing on boot after recent changes in the ACPI processor
     driver (Woody Suwalski)"
