PCC: Initialize PCC Mailbox earlier at boot
This change initializes the PCC Mailbox earlier than the ACPI processor driver. This enables drivers introduced in follow up patches (e.g. CPPC) to be probed via the ACPI processor driver interface. The CPPC probe requires the PCC channel to be initialized for it to query each CPUs performance capabilities.
