interconnect: qcom: Move qcom_icc_xlate_extended() to a common file

Browse Source 
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.
