Summary
serial: arc_uart: fix of_iomap leak in `arc_serial_probe`
Details

In the Linux kernel, the following vulnerability has been resolved:

serial: arcuart: fix ofiomap leak in arc_serial_probe

Smatch reports:

drivers/tty/serial/arcuart.c:631 arcserialprobe() warn: 'port->membase' from ofiomap() not released on lines: 631.

In arcserialprobe(), if uartaddone_port() fails, port->membase is not released, which would cause a resource leak.

To fix this, I replace ofiomap with devmplatformioremapresource.
