ACPI: processor: Downgrade Intel _OSC and _PDC messages to debug

superm1 · rafaeljw · commit c7cfe9bfceb7 · 2024-06-19T16:56:35.000+02:00
Commit 9527264 ("ACPI: processor: Use _OSC to convey OSPM processor support information") introduced messages related to determining processor support from the firmware. The UUID 4077A616-290C-47BE-9EBD-D87058713953 and _PDC methods are only used on Intel platforms, but all X86 platforms emit the messages. Attempting to evaluate them and showing messages on which are used is unnecessary for most users. Downgrade the messages to debug instead.
