spring: Shorten charging state update interval
The condition for the battery to set FULLY_CHARGED bit is:
1. Charge >= 95%
2. V >= 12.3V
3. I < 52mA for 60 seconds
If we hit fastcharge timeout when 1 and 2 are true, the EC has to
respond and restart charging within 60 seconds. Otherwise, the battery
sets FULLY_CHARGED bit and stops charging with charge < 100%.
Let's shorten the update interval for S3/S5 from 60 seconds to 30
seconds. With current 10-second interval for charging state, the EC will
restart charging within 40 seconds.
