Does the issue with the LDB DI mux glitch locking up the LDB DI divider
also affect rev 1.0 silicon?
(http://lists.infradead.org/pipermail/linux-arm-kernel/2014-July/268864.html)

We probably shouldn't touch LDB_DIx_SEL here for the other revisions
either. In any case, this would be a patch for the linux-arm-kernel
mailing list.

Philipp
