AVS Bus divider, loadline and misc changes

- validate CRC in cmd response
- read current / voltage on alternating ticks (commands on both bus for each tick)
- calculate chip power (with loadline) and power for each tick
- update divider value for bus speed
- add error history counters and add them to logs
