arm: omap3: Bring back ARM errata workaround 725233
The workaround for ARM errata 725233 had been lost since
commit 45bf05854bc94e (armv7: adapt omap3 to the new cache
maintenance framework). Bring it back in order to avoid
very difficult to reproduce, but actually encountered in
the wild CPU deadlocks when running software rendered
X11 desktop on OMAP3530 hardware.
