Subject: [PATCH] interconnect: qcom: sdx55: Drop IP0 interconnects
Similar to the sc7180 commit, let's drop the IP0 interconnects here
because the IP0 resource is also used in the clk-rpmh driver on sdx55.
It's bad to have the clk framework and interconnect framework control
the same RPMh resource without any coordination. The rpmh driver in the
kernel doesn't aggregate resources between clients either, so leaving
control to clk-rpmh avoids any issues with unused interconnects turning
off IP0 behind the back of the clk framework.
