Subject: [PATCH v2 2/2] dt-bindings: interconnect: qcom: Drop QPIC_CORE IDs

From: Raviteja Laggyshetty <quic_rlaggysh@...cinc.com>

As like other SDX targets, SDX75 QPIC BCM resource is also modeled as a
RPMh clock in clk-rpmh driver. However, for SDX75, this resource was also
described as an interconnect node mistakenly.

Hence, drop the QPIC interconnect IDs and let the clients use clk-rpmh
driver to vote for this resource.

Even though this change is an ABI break, it is necessary to avoid
describing the same resource provider in two different drivers, as it may
lead to votes from clients overriding each other.
