ARM: ux500 specific L2 cache code

The generic version of l2x0_inv_all is only called just after disabling
the L2 cache and is surrounded by a spinlock. However, we're not really
turning off the L2 cache right now, and the PL310 does not support
exclusive accesses (used to implement the spinlock). So, the
invalidation needs to be done without the spinlock.
