ARM: 7397/1: l2x0: only apply workaround for erratum #753970 on PL310
commit f154fe9b806574437b47f08e924ad10c0e240b23 upstream.
The workaround for PL310 erratum #753970 can lead to deadlock on systems
with an L220 cache controller.
This patch makes the workaround effective only when the cache controller
is identified as a PL310 at probe time.

[bwh: Backported to 3.2: adjust context]
