qpnp-fg-gen3: configure ESR timers dynamically based on charge termination

With ESR discharge timer retry, max having same value, ESR pulse
can fire frequently when battery FET is open past charge
termination. This frequent ESR pulses increase power consumption
when the device is idle.

Upon charge termination, change the ESR discharging timer retry
to 0 so that ESR pulse can fire less frequently saving power.

Add support for this through fg_esr_timer_config() based on end
of charge and sleep conditions.

Currently, retry/max for ESR charging and discharging timers are
configured with the same value specified through device tree.
Extend the device tree property to take in different retry/max
values for those timers.
