net: phy: at803x: simplify using devm_gpiod_get_optional and its 4th argument
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_optional instead of ignoring all errors returned by devm_gpiod_get and simplify accordingly. The result is more strict error handling which is good.
