power: qpnp-fg: do not mask auto recharge bit 



Currently, auto recharge mask bit is enabled by default. This is
causing problems like monotonic SOC getting stuck while charging
under different temperature conditions. Remove the configuration
done on auto recharge mask bit so that it has the configuration
done by bootloader.
