For the panels which backlight is controlled by gpio, add this logic
in driver to turn on/off backlight, instead of calling board panel
on/off functions, to avoid garbage display due to early backlight
turn-on.

mdp clock is controlled by frame work. There has
possibility that mdp clock had been turned off while

will enable mdp clock at pipe commit when mdp clock

Currently, when an underrun occurs, a reset request is sent to the
histogram hardware. This has been observed to cause a hang in the histogram
collection cycle. The fix for this hang is to instead rely on the existing
checks for histogram validity in the histgram read worker. When the
underrun occurs, the histogram is invalidated, which in turn causes the
histogram read worker to reset the histogram collection when it attempts to
read its contents.

With 8974, bandwidth requests are exceeding integer size.
Update ab and ib to ensure values over 4Gbps can be requested.
For 64-bit support, there are four changes in this patch:
Changes in the bus driver structures and functions to
update ab and ib values to uint64.
Updates in client drivers to ensure that the bus APIs
are called with the right types.
Updates to the device-tree. Device-tree nodes don't
provide a clean mechanism to read a combination of u32
and u64 variables within the same property name. So, the
ab and ib values must be specified in kbps instead of
bytes/sec from the device tree. The bus driver function
will convert the ab and ib values read from device-tree
to Mbps.
Change the existing property names to make them consistent
with the convention used by the new property name, which
abides to the Device Tree convention.
