Well, it's about time we got rid of this from platform specific code
anyway, taking it away from platform maintainers to mess around with.
So that's what I'm doing.

It's worth noting that if you build a single zImage with exynos also
enabled, then you also end up with an unconditional call from that
code to l2x0_of_init() with it's own magic numbers - and that applies
before my changes.

So let's fix this properly and yank this crap from platform maintainers
fingers.
