ixp4xx: Break out mv88e6060 DSA switch to package

Browse Source 
Just one of the devices uses the Marvell MV88E6060 DSA
switch so break this out from the generic kernel config
and into a package selected only by that single device
and probed at boot instead.

The big win is from being able to drop the dsa_core
(~600KB) kernel module out of the common kernel on
devices with no DSA switch.
