Replace sysdev classes and struct sys_device objects used for "core"
power management by Samsung platforms with struct syscore_ops objects
that are simpler.
This generally reduces the code size and the kernel memory footprint.
It also is necessary for removing sysdevs entirely from the kernel in
the future.

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.
