Subject: [PATCH 2/4] interconnect: qcom: qcs615: Drop IP0 interconnects

From: Konrad Dybcio <konrad.dybcio@....qualcomm.com>

In the same spirit as e.g. Commit b136d257ee0b ("interconnect: qcom:
sc8280xp: Drop IP0 interconnects"), drop the resources that should be
taken care of through the clk-rpmh driver.

Fixes: 77d79677b04b ("interconnect: qcom: add QCS615 interconnect provider driver")
