net: ftgmac100: select FIXED_PHY

BugLink: https://bugs.launchpad.net/bugs/2120812

commit ae409629e022fbebbc6d31a1bfeccdbbeee20fd6 upstream.

Depending on e.g. DT configuration this driver uses a fixed link.
So we shouldn't rely on the user to enable FIXED_PHY, select it in
Kconfig instead. We may end up with a non-functional driver otherwise.
