Definition: Should contain the following entries:
- "core" Subcore video accelerator clock
- power-domains:
Usage: required for msm8996
Value type: <prop-encoded-array>
Definition: A phandle and power domain specifier pairs to the
power domain which is responsible for collapsing
and restoring power to the subcore.
