Shouldn't we depend on CPU_V7, ARM_GIC and CACHE_PL310 here? I get a lot of
moaning from Kconfig about unmet dependencies. I think the coretiles do have
a CPU etc. on them...

The workarounds for these errata both erroneously depend on CONFIG_SMP; however,
I don't think that's a bug in these patches -- selecting those options here
feels correct.
I'll follow up with some separate patches to fix these.
> + select ARM_ERRATA_753970
Will has a patch, now in Russell's fixes branch, which renames this to
PL310_ERRATA_753970 for compatibility with other people's patches.
This erratum workaround depends on CACHE_PL310, but since the PL310 is
a property of the CoreTile which must be configured in, that dependency
seems reasonable.
