Now that we have a workaround for Hisilicon erratum 161010101, notes
this in the arm64 silicon-errata document.

The new config option is too long to fit in the existing kconfig column,
so this is widened to accomodate it.

I'd like to take this one via arm64, then you can drop it along with the
first patch in the series and I can deal with the conflicts in the text
file.

Daniel, are you ok with that? This file isn't part of the clocksource
code and is purely an informative document that we maintain to help ARM
vendors know which errata we're working around.
