EXYNOS4 supports 3 different system level power down mode by PMU (Power
Management Unit). Each power down mode need to configure many PMU registers
with different value. This patch supports function to configure PMU registers
with pre-defined values in PMU code. This function may be used by PM code and
AFTR/LPA support driver.

Basically, other S3C SoCs and S5PC100 use 'S3C_VA_USB_HSPHY'

usage and others. Now happens build error on S5PC100.

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.
