serial/pch_uart: AT command behavior

[Tomoya MORINAGA]

Hi,

I have a question for UART driver AT command behavior.
When installing pch_uart, AT command "AT+GCAP^M" are sent for 4 times.
This command is sent first install only.
(After the above, removing pch_uart and installing pch_uart again,
this command is not sent.)

Let me know the behavior is normal or not ?

Thanks,
