[PATCH] arm: l2c: unlock ways when in non-secure mode

To boot Linux in Non-secure mode with l2x0, the l2x0 controller is enabled in secure mode and ways locked to make it seems L2 cache disabled during linux boot process. So during l2x0 initialization, need to unlock the ways to make l2x0 could cache data/inst. Signed-off-by: Peng Fan
