interconnect: qcom: Convert to platform remove callback returning void

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Several drivers use qcom_icc_rpmh_remove() as remove callback which
returns zero unconditionally. Make it return void and use .remove_new in
the drivers. There is no change in behaviour.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/dt
Qualcomm ARM64 DT updates for 5.11
For SM8250 the recently introduced support for handling boot-loader
stream mappings in the ARM SMMU allow us to enable this, and thereby USB
controller and PHY, SDHCI controller and FastRPC, as well as support for
the SM8250 HDK board has been added. Additionally PRNG and RTC is
enabled.
Similarly for SM8150, the ARM SMMU could be added which allows the
secondary USB controller and PHYs, as well as WiFi to be added and
support for the SM8150 HDK board to be introduced. Additionally
Coresight and support for the last-level cache controller was added.
MSM8916 finally has VDDCX and VDDMX removed as regulators and are now
handled by the rpmpd driver for the devices controlling them. The
Longsheer L8150 gains touchscreen, sensors, vibrator and LED support.
MSM8992 gains USB and SDHCI support as well as an I2C controller and the
associated RMI4 based touchscreen for the Lumia 950.
MSM8994 also gains USB and SDHCI support, as well as VADC and temp-alarm
support. Then support for the Lumia 950 XL is added.
SDM845 gains interconnect properties for a number of devices and the
GENI wrappers gains iommu stream configuration, which means DMA
operations on e.g. I2C now works. The Lenovo Yoga C630 finally has the
SMMU enabled, a few fixes and the description of the eDP bridge and
panel means that the laptop can now boot mainline with working display,
GPU, WiFi and audio.
SC7180 gains a slew of smaller improvements and fixes.

The QUP nodes are currently defined just as entries in the topology,
but they are not referenced by any of the NoCs. Let's fix this and
"attach" them to their NoCs, so that the QUP drivers are able to use
them as path endpoints and scale their bandwidth.
This is based on the information from the downstream msm-4.9 kernel.

Currently if we use sync_state, by default the bandwidth is maxed out,
but in order to set this in hardware, the BCMs (Bus Clock Managers) need
to be initialized first. Move the BCM initialization before creating the

After enabling interconnect scaling for display on the db845c board,
in certain configurations the board hangs, while the following errors
are observed on the console:
Error sending AMC RPMH requests (-110)
qcom_rpmh TCS Busy, retrying RPMH message send: addr=0x50000
qcom_rpmh TCS Busy, retrying RPMH message send: addr=0x50000
qcom_rpmh TCS Busy, retrying RPMH message send: addr=0x50000
...
In this specific case, the above is related to one of the sequencers
being stuck, while client drivers are returning from probe and trying
to disable the currently unused clock and interconnect resources.
Generally we want to keep the multimedia NoC enabled like the rest of
the NoCs, so let's set the keepalive flag on it too.

Lowering the bandwidth on the bus might have negative consequences if
it's done before all consumers had a chance to cast their vote. Now by
default the framework sets the bandwidth to maximum during boot. We need
to use the icc_sync_state callback to notify the framework when all
consumers are probed and there is no need to keep the bandwidth set to
maximum anymore.
