Hauke Mehrtens 20358be02a bcm53xx: add arm l2c overwrite options like in mainline kernel
Instead of setting the l2c_aux_val variable in the board code make it
possible to set these through device tree and make use of that.

Subject: [PATCH 72/74] ARM: l2c: clean up l2c_configure()
l2c_configure() does not follow the pattern of other l2c_* functions.
Fix this so that it does to avoid future confusion.
