Subject: [PATCH v3] interconnect: qcom: qcs8300: fix the num_links for nsp
 icc node

The qxm_nsp node is configured with an incorrect num_links value,
causing remoteproc driver to fail probing because it cannot acquire the
interconnect path for qxm_nsp -> ebi. This results in the following
error in dmesg:

  platform 26300000.remoteproc: deferred probe pending:
  qcom_q6v5_pas: failed to acquire interconnect path

Set num_links to 2 to match the two link_nodes, allowing remoteproc
clients to obtain the correct path handle and vote on qxm_nsp -> ebi.

Fixes: 874be3339c85 ("interconnect: qcom: qcs8300: convert to dynamic IDs")
