mailbox: pcc: Drop uninformative output during boot
When booting on an ACPI enabled system that does not provide the Platform Communications Channel Table (PCCT), the pcc mailbox driver prints - [ 0.484261] PCCT header not found. during probe before returning -ENODEV. This message clutters the bootlog and doesn't provide any useful information. Drop this message.
