[PATCH v3] gemini: Convert to use module for Realtek switch

[Linus Walleij]

Only the DIR-685 uses a Realtek DSA switch currently so
convert this platform to load it from a module and save
memory on all other devices.

At the same time drop the rt2800 PCI package that this
device actually isn't using, it needs an out-of-tree
wireless driver.

Not all Gemini platforms are using a DSA switch, so
by converting the switches into packages and just selecting
that package for the one device needing it we save a lot
of space (600KB+) on all other devices.
