ACPI: PCC: replace wait_for_completion()
Currently, the function waiting for completion of mailbox operation is
'wait_for_completion()'. The PCC method will be permanently blocked if
this mailbox message fails to execute. So this patch replaces it with
'wait_for_completion_timeout()'. And set the timeout interval to an
arbitrary retries on top of nominal to prevent the remote processor is
slow to respond to PCC commands.
