[PATCH 07/11] media: qcom: iris: split HFI session ops from core ops

[Dmitry Baryshkov]

Calling HFI instance-specific ops should not require double indirection
through the core ops. Split instance-specific ops to a separate struct,
keep a pointer to it in struct iris_inst and set it directly in the
get_instance function.
