net: Add depends on OF_NET for LiteX's LiteETH

Current settings may produce a build error when
CONFIG_OF_NET is disabled. The CONFIG_OF_NET controls
a headfile <linux/of.h> and some functions
in <linux/of_net.h>.

Hi Maxim,
We're looking to turn down our old @googlegroups.com mailing list. Any
chance these reports can instead be sent to ll...@lists.linux.dev so
that they are archived by lore.kernel.org?

Hi Nick,

We have changed our infrastructure to email ll...@lists.linux.dev on the 6th of September [1]. The email you reported seems to have been sent before that (on the 2nd of September). Newer emails ought to go to the right place, please let us know if you find emails to @googlegroups from jobs started after the 6th of September.

Cheers,

Diana
