[4/6,v2] ARM: ux500: select L2X0 cache on ux500

From: Arnd Bergmann <arnd@arndb.de>

The cache controller needs to be enabled for the
cortex-a9 specific errata that are also selected
to work.

Also correcting config name for errata 753970.

Hey wait, that renaming fixes a regression introduced in commit
fa0ce4035d4897b0642132866d896a906429f45e
"ARM: 7162/1: errata: tidy up Kconfig options for PL310 errata workarounds"

Please:

(1) Fix this also in arch/arm/mach-vexpress/Kconfig where we
  have the same problem.

(2) Get Will Deacon's ACK

(3) Put it into Russell's patch tracker for immediate fixes.

Yours,
Linus Walleij

I beat you to it :) Check out 43a6955f ("ARM: 7346/1: errata: fix PL310
erratum #753970 workaround selection") in rmk/fixes.

Cheers,
