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.

It doesn't contain why don't need to require it. If you add more detailed
description, it is better to understand.
