c8fd5a3734 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.

cff66ace51 interconnect: Explicitly include correct DT includes
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.

0dc82bd9e4 interconnect: qcom: sm8550: add enable_mask for bcm nodes
Set the proper enable_mask to nodes requiring such value
to be used instead of a bandwidth when voting.

The masks were copied from the downstream implementation at [1].

0d00cd114f interconnect: qcom: sm8550: switch to qcom_icc_rpmh_* function
Change sm8550 interconnect driver to use generic qcom_icc_rpmh_*
functions rather than embedding a copy of thema. This also fixes an
overallocation of memory for icc_onecell_data structure.
