[PATCH] net: phy: at803x: don't depend on GPIOLIB

[Sebastian Frias <sf84@laposte.net>]

Commit 687908c2b649 ("net: phy: at803x: simplify using
devm_gpiod_get_optional and its 4th argument") introduced a dependency
on GPIOLIB that was not there before.

This commit removes such dependency by checking the return code and
comparing it against ENOSYS which is returned when GPIOLIB is not
selected.

Fixes: 687908c2b649 ("net: phy: at803x: simplify using
devm_gpiod_get_optional and its 4th argument")
