Add interconnect-cells to clock provider so that it can be
used as icc provider.

Add master/slave ids for Qualcomm IPQ9574 Network-On-Chip
interfaces. This will be used by the gcc-ipq9574 driver
that will for providing interconnect services using the
icc-clk framework.

v8:
Remove ICC_xxx macros
Fix macro defines to be consistent with other bindings
v7:
Fix macro names to be consistent with other bindings
v6:
Removed Reviewed-by: Krzysztof Kozlowski
Redefine the bindings such that driver and DT can share them

v3:
Squash Documentation/ and include/ changes into same patch

qcom,ipq9574.h
	Move 'first id' to clock driver

I still do not see any usage of it. At least symbol cannot be resolved.
I assume you use the value, otherwise it would mean our entire feedback
was ignored, but then why this cannot be searchable?

Again, open existing drivers and look how it is there. Not being able to
find the constant is not good.

Best regards,
Krzysztof

It is used in the 6th patch in drivers/clk/qcom/gcc-ipq9574.c via the
HWS_DATA macro. Will remove the macro and use it explicitly (as suggested
by Dmitry also).
