These SoCs are network packet processors (switch chips) with integrated
ARMv7 cores. They share a great deal of commonality with the Armada-XP
CPUs.

There are actually a number of IDs for these chips, probably a dozen in
total. I haven't enumerated them all in this patch, the 98DX4251,
98DX3336 and 98DX3236 are the base versions in their respective ranges.
These 3 IDs also happen to suit my immediate need but I can add the
additional ones in an follow up patch or a re-roll of this one.
