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.

Fixes: fafc114a468e ("interconnect: qcom: Add SM8450 interconnect provider driver")
