[v2,2/2] interconnect: qcom: Use icc_sync_state in sdm845 and osm-3l drivers

Commit Message

Lowering the bandwidth on the bus might have negative consequences if
it's done before all consumers had a chance to cast their vote. Let's
return the maximum amount of bandwidth as initial value. This bandwidth
level would be maintained until all consumers have probed.
