[PATCH][wwwdocs] Add Cortex-A53 erratum workaround note to AArch64 changes for 4.8

Hi all,

Considering that the erratum workaround option was backported to 4.8, I 
assume we'll need an item for that
in the changes.html for that branch?

The text is the same as in the trunk version that I committed recently.

Ok?
Thanks,
Kyrill

Good point.

Yes.  It will be good note note which minor release is the first
with this fix, though.

Makes sense. Here are the changes for the 4.9 and 4.8 changes.html pages.

Ok?

This looks ok to me, I'd suggest changing...

+  <li> Starting with GCC 4.8.4 a workaround for the ARM Cortex-A53

to

+ <li> As of GCC 4.8.4 ....

OK with that change.
