Stephen Boyd 418db40cc7 interconnect: Restore sync state by ignoring ipa-virt in provider count
commit 20ce30fb4750f2ffc130cdcb26232b1dd87cd0a5 upstream.

Ignore compatible strings for the IPA virt drivers that were removed in
commits 2fb251c26560 ("interconnect: qcom: sdx55: Drop IP0
interconnects") and 2f3724930eb4 ("interconnect: qcom: sc7180: Drop IP0
interconnects") so that the sync state logic can kick in again.
Otherwise all the interconnects in the system will stay pegged at max
speeds because 'providers_count' is always going to be one larger than
the number of drivers that will ever probe on sc7180 or sdx55. This
fixes suspend on sc7180 and sdx55 devices when you don't have a
devicetree patch to remove the ipa-virt compatible node.
