media: qcom: camss: Add per sub-device type resources

Currently resources structure grows with additional parameters required for
each sub-deivce. However each sub-device has some specific resources or
configurations which need to be passed during the initialization.

This change adds per sub-device type structure to simplify the things
and removes the magical void pointer to hw_ops.
