This patch includes the implementation of the clock gating for System MMU. Initially, all System MMUs are not asserted the system clock. Asserting the system clock to a System MMU is enabled only when s5p_sysmmu_enable() is called. Likewise, it is disabled only when s5p_sysmmu_disable() is called. Therefore, clock gating on System MMUs are still invisible to the outside of the System MMU driver.
