power: pm8921-bms: fix fake battery emulation

With the recent split of functions to calculate and report state of
charge, the faking battery feature broke, it remained in the calculate
function.

Move the fake battery feature in the reporting function, where it really
belongs.

power: pm8921-charger: fix EOC worker not starting

There are situations when we observe that charging is in progress
but the end of charge (EOC) worker is not running. This leads to
problems like
-never detecting end of charge
-not adjusting vddmax
-not preventing suspend while charging.

The reason is that the bootloader could have started charging already,
causing a fastchg interrupt to not happen. If the fastchg interrupt is
missed the driver will never start EOC worker.

Check the real time status of the fastchg interrupt and if it is fast
charging invoke the handler so that the eoc worker could be
started.

power: pm8921-charger: Control CHG_USB_SUSPEND enabling boost

Toggle the CHG_USB_SUSPEND bit when utilizing the VBUS boost.
This bit controls ensures that no current is being drawn from
a USB device and the charger runs off the battery.

This makes sure that when pm8921_disable_source_current is called
the correct setting is written to the suspend bit depending
on the disable flag.

Bluetooth: Fixes FindMe Target L2CAP channel issue

When whitelist APIs are used for establishing LE connection
between the phone and remote LE device, few times
ATT requests like Read by Group Type request are received by
the phone from the remote device before the L2CAP channel has
been set up completely. Hence the LE server in the phone
sends a "Request not supported" error response since
the L2CAP channel has not yet been created. This fix checks
the state of the L2CAP channel after sleeping for a while
and sends the ATT request to be processed by the upper layers
when the L2CAP channel is up.
