When Linux is running in the non-secure world, any write to a secure L2C register will generate an abort. Platforms normally have to call firmware to work around this. Provide a hook for them to intercept any L2C secure register write. l2c_write_sec() avoids writes to secure registers which are already set to the appropriate value, thus avoiding the overhead of needlessly calling into the secure monitor.
