Preserve the contents of the xo_div4 register. Downstream kernel
preserves the contents of the register. Writing just 1 makes the msm8996
report the value divided by 4 rather than the actual clock frequency.

Add a way to print clocks related to a particular CC. Add -b option,
which takes 'block' name: cam, disp, cpu, gpu, video. Pass "-b core" to
limit debugcc to "core" (gcc) clocks.

Add in msm8936 downstream clock-mapping definitions. This also covers
msm8939, at the level of the fundamental clock layout, there is no
difference between msm8936 and msm8939.

It looks like post_div_val is a property of debug_mux rather than the
clock itself. It is equal for all the clocks being set. So, set it on a
mux-by-mux bases.

The common boiler plate code provides the means for measuring clocks
using the debugcc feature on various Qualcomm platforms.
