[PATCH net-next] net: ethernet: fs_enet: Make the per clock optional

[Maxime Chevallier]

Some platforms that use fs_enet don't have the PER register clock. This
optional dependency on the clock was incorrectly made mandatory when
switching to devm_ accessors.

Closes: https://lore.kernel.org/netdev/4e4defa9-ef2f-4ff1-95ca-6627c24db20c@wanadoo.fr/
