[PATCH -next] serial: etraxfs-uart: Update gpiod API

[Guenter Roeck <linux@roeck-us.net>]

Commit b17d1bf16cc7 ("gpio: make flags mandatory for gpiod_get functions")
makes the flags argument to devm_gpiod_get_optional mandatory but does not
update all users. This results in the following build error.

drivers/tty/serial/etraxfs-uart.c:933:16: error:
	too few arguments to function ‘devm_gpiod_get_optional’

Fixes: b17d1bf16cc7 ("gpio: make flags mandatory for gpiod_get functions")
