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.

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.

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.

Pointers to struct qcom_icc_bcm are not modified, so they can be made
const for safety. The contents of struct qcom_icc_bcm must stay
non-const.

Add driver for the Qualcomm interconnect buses found in SM8450 based
platforms. The topology consists of several NoCs that are controlled by
a remote processor that collects the aggregated bandwidth for each
master-slave pairs.
This is based on the downstream driver by
