qcom-charger: qpnp-fg-gen3: increase ESR timer during suspend
ESR pulses consume too much power during sleep states.
Add device tree properties to allow configuration of the ESR timing during
charging, discharging while awake, and discharging while asleep.
Configure these new device tree properties to increase the ESR timer
while in a sleep state to save power.
