Subject: [RFC PATCH v3 2/7] interconnect: Relax requirement in
 of_icc_get_from_provider()

This patch relaxes the condition in of_icc_get_from_provider() so that it
is no longer required to set #interconnect-cells = <1> in the DT. In case
of the devfreq driver for exynos-bus, #interconnect-cells is always zero.
