Subject: [PATCH v2] ACPI: Downgrade Intel _OSC and _PDC messages to debug

commit 95272641338a ("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.
