X1P42100 video clock controller has most clocks same as SM8650,
but it also has few additional clocks and resets. Add device
tree bindings for the video clock controller on Qualcomm
X1P42100 platform by defining these additional clocks and resets
on top of SM8650.

I checked a number of platforms and the _BSE clocks are only present on
Purwa, without any explanation in the corresponding docs.

What are they used for?

These clocks are used to drive Bin stream engine, which is a sub-block of
video codec HW, which seems to be present only on Purwa.
