Doug Anderson 416bcf2159 ARM: 8559/1: errata: Workaround erratum A12 821420 
This erratum has a very simple workaround (set a bit in a register), so
let's apply it.  Apparently the workaround's downside is a very slight
power impact.

Note that applying this errata fixes deadlocks that are easy to
reproduce with real world applications.

The arguments for why this needs to be in the kernel are similar to the
arugments made in the patch "Workaround errata A12 818325/852422 A17
852423".
