interconnect: constify of_phandle_args in xlate

The xlate callbacks are supposed to translate of_phandle_args to proper
provider without modifying the of_phandle_args. Make the argument
pointer to const for code safety and readability.

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.
