Merge branch 'icc-ip0-migration' into icc-next

Commits 2f372493 ("interconnect: qcom: sc7180: Drop IP0
interconnects") and 2fb251c2 ("interconnect: qcom: sdx55: Drop IP0
interconnects") removed IP0 interconnects (and ipa-virt devices support)
in favour of the RPMH clocks. Follow this example for other platforms
defining IP0 RPMH resource. While we are at it, remove several leftover
from the mentioned patches.

* icc-ip0-migration:
  interconnect: qcom: sdx55: drop IP0 remnants
  interconnect: qcom: sc7180: drop IP0 remnants
  interconnect: move ignore_list out of of_count_icc_providers()
  interconnect: qcom: sm8150: Drop IP0 interconnects
  interconnect: qcom: sm8250: Drop IP0 interconnects
  interconnect: qcom: sc8180x: Drop IP0 interconnects
  interconnect: qcom: sc8280xp: Drop IP0 interconnects
  dt-bindings: interconnect: qcom: Remove ipa-virt compatibles
  dt-bindings: interconnect: qcom: drop IPA_CORE related defines
