James Morse 285e77dbb3 arm64: errata: Add Cortex-A510 to the repeat tlbi list
commit 39fdb65f52e9a53d32a6ba719f96669fd300ae78 upstream.

Cortex-A510 is affected by an erratum where in rare circumstances the
CPUs may not handle a race between a break-before-make sequence on one
CPU, and another CPU accessing the same page. This could allow a store
to a page that has been unmapped.

Work around this by adding the affected CPUs to the list that needs
TLB sequences to be done twice.
