net: sparx5: add missing lan969x Kconfig dependency

The sparx5 switchdev driver can be built either with or without support
for the Lan969x switch. However, it cannot be built-in when the lan969x
driver is a loadable module because of a link-time dependency:

arm-linux-gnueabi-ld: drivers/net/ethernet/microchip/sparx5/sparx5_main.o:(.rodata+0xd44): undefined reference to `lan969x_desc'

Add a Kconfig dependency to reflect this in Kconfig, allowing all
the valid configurations but forcing sparx5 to be a loadable module
as well if lan969x is.
