[PATCH] net: NET_VENDOR_LITEX should depend on LITEX

[PATCH] net: NET_VENDOR_LITEX should depend on LITEX

[Geert Uytterhoeven]

LiteX Ethernet devices are only present on LiteX SoCs.  Hence add a
dependency on LITEX, to prevent asking the user about drivers for these
devices when configuring a kernel without LiteX SoC Builder support.

Fixes: ee7da21ac4c3be1f ("net: Add driver for LiteX's LiteETH network interface")

nak.

They can be present on any soc that uses them. We have an example in
mainline already; microwatt uses liteeth but is not a litex soc.

But liiteeth.c uses <linux/litex.h>?
And https://github.com/enjoy-digital/litex can be used with a microwatt
CPU core?

The idea behind the LITEX config symbol was to gate off any driver
using LiteX interfaces.
