interconnect: qcom: qcm2290: Enable sync state

[ Upstream commit 4e048e9b7a160f7112069c0ec2947be15f3e8154 ]

Enable the generic .sync_state callback to ensure there are no
outstanding votes that would waste power.

Generally one would need a bunch of interface clocks to access the QoS
registers when trying to go over all possible nodes during sync_state,
but QCM2290 surprisingly does not seem to require any such handling.
