net: lan969x: add match data for lan969x

Browse Source 
Add match data for lan969x, with initial fields for iomap, iomap_size
and ioranges. Add new Kconfig symbol CONFIG_LAN969X_CONFIG for compiling
the lan969x driver.

It has been decided to give lan969x its own Kconfig symbol, as a
considerable amount of code is needed, beside the Sparx5 code, to add
full chip support (and more will be added in future series). Also this
makes it possible to compile Sparx5 without lan969x.
