16862f1b21 interconnect: qcom: sm8450: Enable sync_state
Enable sync_state on sm8450 so that the interconnect votes actually mean
anything and aren't just pinned to INT_MAX.

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.

be02db24cf interconnect: qcom: sm8450: 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].

87e8fab191 interconnect: qcom: sm8450: switch to qcom_icc_rpmh_* function
Change sm8450 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.

fa80a2994d interconnect: sm8450: Ignore return value of icc_provider_del() in .remove()
icc_provider_del() already emits an error message on failure. In this
case letting .remove() return the corresponding error code results in
another error message and the device is removed anyhow. (See
platform_remove().)

So ignore the return value of icc_provider_del() and return 0
unconditionally.

This is a preparation for making platform remove callbacks return void.

cb4805b5a5 interconnect: qcom: Move qcom_icc_xlate_extended() to a common file
since there have conflict between two headers icc-rpmh.h and icc-rpm.h,
the function qcom_icc_xlate_extended() is declared in icc-rpmh.h thus
it cannot be used by icc-rpm driver.

Move the function to a new common file icc-common.c so that allow it to
be called by multiple drivers.
