SDM710: Reduce the spam charger related logs

Browse source 
When charger plugged in or not, Below logs are seen
flooded in the kernel logs accordingly.
One log for every 10 seconds would get printed even when
there is no change in the charger rate state.

Solution:
dump the logs when there is actual change in charger present state
and charge rate.
