[ Upstream commit 05123e3299dd6aa02508469b303262338c2a661c ]

Return -EPROBE_DEFER from interconnect provider incase probe defer is
received from devm_clk_bulk_get_all(). This would help in reattempting
the inteconnect driver probe, once the required QoS clocks are
available.

[ Upstream commit d3681b30214eb5885092ce4586f07237dc3c522f ]

Enable the generic icc sync_state callback to ensure interconnect votes
are actually taken into account, instead of being forced to the maximum
value.

This series adds QoS support for QNOC type device which can be found on
SC7280 platform. It adds support for programming priority,
priority forward disable and urgency forwarding. This helps in
priortizing the traffic originating from different interconnect masters
at NOC (Network On Chip).

Add qos_clks_required flag to skip QoS configuration if clocks property
is not populated in devicetree for providers which require clocks to be
enabled for accessing registers. This is to keep the QoS configuration
backwards compatible with devices that have older DTB.

Add driver for interconnect busses found in MSM8953 based platforms.
The topology consists of four NoCs that are partially controlled by a
RPM processor.

Note that one of NoCs (System NoC) has a counterpart (System NoC MM)
that is modelled as child device to avoid resource conflicts, since it
uses same MMIO space for configuration.
