Modify the cpufreq.c driver to save and restore any user modified
scaling_max_freq and scaling_min_freq when CPU hotplugging. By
default, any cap on maximum scaling frequency is removed when a CPU is
taken offline and then brought back online again and the physical
maximum or minimum frequency is restored instead. This patch changes
that behaviour.

Change from KOBJ_POLICY_INIT to KOBJ_ONLINE as ueventd ignores the
POLICY_INIT event. This results in the sysfs permissions for the
CPU frequency and governor not being set correctly and breaks the
PowerHAL power management function.

* Update v4l2 driver to conform to Samsung Treltexx sources.
* Remove non-existent VIDEO_EXT secmem region

The imported code had additional code that appears to belong
to a different SoC. The code in question was spread out
across the exynos-ion driver, the secmem driver and the Exynos
MFC driver. It was causing attempts to access non-existent
contiguous memory regions, attempts to create secure sysmmu
page tables in these non-existent regions and attempts to
allocate protected memory, all of which failed.

The symptom is failure to instantiate all Exynos hardware
video codecs. This backport of Samsung treltexx sources
fixes the failure to instantiate hardware video codecs

Turns out the previous patch did not handle all crash cases and we
need a more aggressive approach to this.

As documented in s5p_mfc_common.h, dev->curr_ctx_drm is the
number of the currently running (DRM) context.
However, s5p_mfc_pm.c notes that s5p_mfc_clock_on_with_base
may only ever be called if we can guarantee to handle the
first instance.
Thus, we employ a check to only allow s5p_mfc_clock_on_with_base
if the number of (DRM) contexts indicates one instance.

I have no idea how Samsung works around this in userspace
in their Marshmallow libraries.
However, the new code (just turning the clocks off/on) causes
a sysmmu write page fault with out current BSP.

It looks like the new method (s5p_mfc_clock_on_with_base)
should handle the DRAM address change, but it doesn't.
