interconnect: Restore sync state by ignoring ipa-virt in provider count
[ Upstream commit20ce30fb47
] Ignore compatible strings for the IPA virt drivers that were removed in commits2fb251c265
("interconnect: qcom: sdx55: Drop IP0 interconnects") and2f3724930e
("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.
