interconnect: qcom: Configure QoS when provider is sync stated

In the current code, QoS configuration is attempted before the votes
for MM0 are in place. That's why we may observe some hangs during boot.
Move all QoS configuration to happen during the sync_state to ensure
that the keepalive votes are already in place and also enable the
relevant interface clocks while we setup QoS.
