interconnect fixes for v6.7-rc

This contains fixes for reported issues. One fix is in framework code to
explicitly treat returned NULL nodes as error when the device-tree data
is translated into endpoint nodes.
The other two fixes are in driver code. One is expected to improve the
power consumption on the sm8250 platforms and the other one is fixing a
bandwidth calculation formula that was introduced during this cycle.

- interconnect: Treat xlate() returning NULL node as an error
- interconnect: qcom: sm8250: Enable sync_state
- interconnect: qcom: icc-rpm: Fix peak rate calculation
