A error, "Client can't run the TX ticker", is printed even if PCC command

the Tx ACK interrupt. So this patch fix it.
Thanks for fixing this. Someone mentioned about the error and it was in
my TODO list.
Great minds think alike😁
I would prefer to reword the subject and commit message as below:
"
ACPI: PCC: Fix Tx acknowledge in the PCC address space handler
Currently, mbox_client_txdone() is called from the PCC address space
handler and that expects the user the Tx state machine to be controlled
by the client which is not the case and the below warning is thrown:
| PCCT: Client can't run the TX ticker
Let the controller run the state machine and the end of Tx can be
acknowledge by calling mbox_chan_txdone() instead.
"
Thank you for your suggestion. I will fix it in V2.
With that:
