ARM: zynq: Drop use of slcr_unlock in zynq_slcr_system_restart
The SLCR is unconditionally unlocked early on boot in zynq_slcr_init() and not ever re-locked. As such, it is not necessary to explicitly unlock in the restart codepath. Signed-off-by: Josh Cartwright <joshc@ni.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com>
