interconnect: Allow inter-provider pairs to be configured
This patch adds support for a new boolean 'inter_set' field in struct icc_provider. Setting it to 'true' enables calling '->set' for inter-provider node pairs. All existing users of the interconnect framework allocate this structure with kzalloc, and are therefore unaffected by this change. This makes it easier for hierarchies like exynos-bus, where every bus is probed separately and registers a separate interconnect provider, to model constraints between buses.
