Invoke the GPD_OFF_PRE/GPD_ON_POST power Domain notifiers. This will
allow some clocks to be saved and restored. These notifiers can also
be invoked from the core power domain files but is not done as exynos is
the only user of these notifiers as of now.
In exynos7 SOC's only GPD_OFF_PRE/GPD_ON_POST are required.
