Thomas Petazzoni c8f5a878e5 ARM: mvebu: use DT properties to fine-tune the L2 configuration
In order to optimize the L2 cache performance, this commit adjusts the
configuration of the L2 on the Cortex-A9 based Marvell EBU processors
(Armada 375, 38x and 39x), using the appropriate DT properties.

We enable double linefill, incr double linefill, data prefetch and
disable double linefill on wrap. This matches the configuration that
was fine tuned in the Marvell BSP.
