[PATCH] net: phy: at803x: simplify using devm_gpiod_get_optional and its 4th argument

["Uwe Kleine-König" <u.kleine-koenig@pengutronix.de>]

Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions)
which appeared in v3.17-rc1, the gpiod_get* functions take an additional
parameter that allows to specify direction and initial value for output.
Moreover use devm_gpiod_get_index_optional instead of ignoring all
errors returned by devm_gpiod_get. Simplify accordingly.

The result is more strict error handling which is good.
