Subject: [PATCH v2 2/2] interconnect: qcom: qcm2290: Enable sync state

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.

Fixes: 1a14b1ac3935 ("interconnect: qcom: Add QCM2290 driver support")
