ARM: 7196/1: errata: Remove SMP dependency for erratum 720789
Activation conditions for a workaround should not be encoded in the workaround's direct dependencies if this makes otherwise reasonable configuration choices impossible. The workaround for erratum 720789 only affects a code path which is not active in UP kernels; hence it should be safe to turn on in UP kernels, without penalty. This patch simply removes the extra dependency on SMP from Kconfig. This means that configs for buggy silicon can simply select ARM_ERRATA_720789, without preventing a UP kernel from being built or duplicatiing knowledge about when to activate the workaround.

This option enables the workaround for the 720789 Cortex-A9 (prior to
r2p0) erratum. A faulty ASID can be sent to the other CPUs for the
