ARM: BCM5301X: activate some additional options in pl310 cache controller
In the default Broadcom SDK the shared override is activated for this cache controller, do the same in the upstream code. Data and instruction prefetching is not activated by default for this cache controller on the bcm53xx SoC, do it manually like it is done in the vendor SDK.
