[PATCH] ARM: mvebu: rename ARM_ERRATA_753970

[Paul Bolle]

ARM_ERRATA_753970 was renamed to PL310_ERRATA_753970 in v3.2, through
commit fa0ce4035d48 ("ARM: 7162/1: errata: tidy up Kconfig options for
PL310 errata workarounds"). Two selects were added in v3.15-rc1 that
still use the previous name. Rename these.

Make these statements depend on CACHE_PL310, like all other selects of
PL310_ERRATA_753970. That way it will only be selected if its dependency
is met.

I reported this before v3.15-rc1. I don't know whether any fixes are
pending. None are in linux-next. And ignoring an errata were one
apparently could be needed sounds, well, scary. Perhaps it is not.
Anyhow, to make sure this gets fixed, hopefully before v3.15, I'm
submitting this (untested!) patch.

A related observation. There are three PL310 errata options: one depends
on CACHE_PL310, three depend on CACHE_L2X0. The one depending on
CACHE_PL310 is selected only if CACHE_PL310 is set.

But the three depending on CACHE_L2X0 are selected a few times if
CACHE_L2X0 is set, in other cases if CACHE_PL310 is set, and in some
cases always. There may be good reasons for this, but it looks odd. I
know nothing about the PL310 cache and its erratas, so I haven't looked
into this any further.
