ARM: 7197/1: errata: Remove SMP dependency for erratum 751472
Activation conditions for a workaround should not be encoded in the workaround's direct dependencies if this makes otherwise reasonable configuration choices impossible. This patches uses the SMP/UP patching facilities instead to compile out the workaround if the configuration means that it is definitely not needed. This means that configs for buggy silicon can simply select ARM_ERRATA_751472, without preventing a UP kernel from being built or duplicatiing knowledge about when to activate the workaround. This seems the correct way to do things, because the erratum is a property of the silicon, irrespective of what the kernel config happens to be.

This option enables the workaround for the 751472 Cortex-A9 (prior
to r3p0) erratum. An interrupted ICIALLUIS operation may prevent the
