Cc: Vikash Garodia, Tomasz Figa, Stanimir Varbanov
Redesign core (vcodec) clock control to give the venus core more
freedom to control them in order to make possible to use core
selection feature on Venus IP v4.
Move all clock and pmdomain functions in separate file and abstract
power control with common operations per Venus IP version.

From: Aniket Masule <amasule@codeaurora.org>
Presently the core (vcodec pipelines) assignment is static. Here we
introduce dynamic load balancing across the cores depending on the
current session load. The load on earch core is calculated and core
with minimum load is assigned to given instance. This will be
applicable on Venus v4 with more than one vcodec cores.

Cc: Vikash Garodia, Tomasz Figa, Aniket Masule, Stanimir Varbanov
From: Aniket Masule <amasule@codeaurora.org>
Handle 10bit video streams in the decoder by using dithering, i.e
the decoder output buffers will be in 8bit format.
The runtime handling is implemented by sending v4l2 event to
userspace application, then the application should stop the
streaming on capture queue and initiate format negotiation, and
start streaming again.
