hatch: Enable CONFIG_CHARGER_BQ25710_IDCHG_LIMIT_MA
This CL enables CONFIG_CHARGER_BQ25710_IDCHG_LIMIT_MA with a 8192 mA limit.
With his config enabled, the bq25710 will be kept in performance mode
when the AP is in S0. The IDCHG (battery current) prochot trigger is
activated and whenever the battery current draw spikes above 8192 mA,
prochot will be asserted for its defined pulse width (default is 10
msec).
BUG=b:132197575
BRANCH=none
TEST=Was tested at the factory on battery only. When the battery SOC
was less than 5% the unit failed to boot 5 out 5 attempts. Using this
CL to enable IDCHG prochot, the unit booted successfully in same
scenario on all 5 attempts.
