This series converts all platform drivers below drivers/interconnect to
use .remove_new(). Compared to the traditional .remove() callback
.remove_new() returns no value. This is a good thing because the driver
core doesn't (and cannot) cope for errors during remove. The only effect
of a non-zero return value in .remove() is that the driver core emits a
warning. The device is removed anyhow and an early return from .remove()
usually yields resource leaks and/or use-after-free bugs.

See commit 5c5a7680e67b ("platform: Provide a remove callback that
returns no value") for an extended explanation and the eventual goal.

All drivers converted here already returned zero unconditionally in
.remove(), so they are converted here trivially. The imx drivers could
be slightly simplified, because the remove callback only called a single
function with the same prototype as .remove_new().

interconnect: qcom/osm-l3: 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().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

interconnect changes for 6.6

This pull request contains the interconnect changes for the 6.6-rc1 merge
window which is a mix of core and driver changes with the following highlights:

Core changes:
- New generic test client driver that allows issuing bandwidth requests
between endpoints via debugfs.
- Annotate all structs with flexible array members with the __counted_by
attribute.
- Introduce new icc_bw_lock for cases where we need to serialize bandwidth
aggregation and update to decouple that from paths that require memory
allocation.

Driver changes:
- Move the Qualcomm SMD RPM bus-clocks from CCF to interconnect framework
where they actually belong. This brings power management improvements
and reduces the overhead and layering. These changes are in immutable
branch that is being pulled also into the qcom tree.
- Fixes for QUP nodes on SM8250.
- Enable sync_state and keepalive for QCM2290.
- Enable sync_state for SM8450.
- Improve enable_mask-based BCMs handling and fix some bugs.
- Add compatible string for the OSM-L3 on SDM670.
- Add compatible strings for SC7180, SM8250 and SM6350 bandwidth monitors.
- Expand and retire the DEFINE_QNODE and DEFINE_QBCM macros, which have
become ugly beasts with many different arguments.

interconnect: qcom: Annotate struct icc_onecell_data with __counted_by

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

As found with Coccinelle[1], add __counted_by for struct icc_onecell_data.
Additionally, since the element count member must be set before accessing
the annotated flexible array member, move its initialization earlier.

As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h

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.
