The USB power_supply object should be maintained by the
charger driver. Since it is now removed from the USB
controller driver, create and register it here. Many
of the calls to set/get_property can be simplified since
there are equivalent state variables we have access to.
PROP_OTG can be removed entirely since that is now handled
by emitting an EXTCON_USB_HOST notification.

Currently, rslow compensation active settings are applied and
cleared based on certain conditions. However, if the device goes
for a reset, the flag used by FG driver to save the setting done
will vanish. For e.g. if an active setting is applied and the
device goes for a reset, even if there is a condition present to
clear the active setting, it will not be applied. This is due to
the fact that the flag (rslow_comp.active) is not set in first
place even though FG HW has that setting applied. Fix this by
reading rslow configuration during hw_init and set the flag.

Currently, ESR is being under-estimated when the battery state of
charge (SOC) is less than 2%. Add a change which can do tuning to
use default ESR values when SOC is less than 2% and switch back
to ESR extraction when SOC goes above 2%. When the SOC is greater
than 2% and less than 5%, apply slow settings for ESR pulse. When
the SOC crosses 5%, apply the default settings.
This will allow the SOC to increase more accurately when the FG
starts with a better ESR value. This feature is supported via
device tree property "qcom,esr-pulse-tuning-en".

Currently, a battery profile is loaded when the profile integrity
bit is not present, a new battery is inserted, or battery voltage
is not in range across reboot. When the battery profile loading
happens after the device has booted up, the charger driver is
notified to disable battery charging.
However, in cases like offline mode charging, the device can boot
up again with charging enabled causing battery parameters to be
modified even before the charger driver can probe. This causes
a jump in state of charge (SOC) across reboot and causes the FG
to restart. To help with this scenario, make sure the charger
driver is ready, and charging is kept disabled before the battery
profile loading process start. Enable charging back when there is
no need to reload the battery profile, or the FG has restarted
and the first SOC estimate is done.

When the charger driver haven't been probed yet and batt_psy is
unavailable, batt_profile_init is rescheduled as it depends on
the charger to disable charging while loading profile. However,
this adds a constraint that SRAM parameters needs to be updated
every time just before batt_profile_init is called again. Else,
stale SRAM parameters will be used to decide whether the battery
profile can be loaded or not.
Hence, cancel and schedule the update_sram_data work whenever
battery profile loading is rescheduled again.
