[PATCH] net: ethernet: litex: Add the dependency on HAS_IOMEM

The helper function devm_platform_ioremap_resource_xxx()
needs HAS_IOMEM enabled, so add the dependency on HAS_IOMEM.

Fixes: 464a57281f29 ("net/mlxbf_gige: Make use of devm_platform_ioremap_resourcexxx()")

That looks wrong...

That's a strange commit message for the litex driver. Similarly for
the ni driver. Did something go wrong there?

A better fixes line would be ee7da21ac4c3be1f618b6358e0a38739a5d1773e,
as the original driver addition also has the iomem dependency.

no, ni driver has the dependency on HAS_IOMEM in
drivers/net/ethernet/ni/Kconfig.

ok.
Thanks
