As fingerprint HAL need read and write fpc1020 sys entries, so those
sys entries need change owner and group to system.
If DLKM is used, after rmmod and insmod fpc1020 kernel module again,
owner and group will be root again for those sys entries.
One way to fix this is set those sys entries owner and group in
uevent.rc.
uevent.rc need be triggered by a device add uevent. So create a
fingerprint class device and move original sys entries to a class device

This issue is due to the race between power_supply_changed()
and smb_mmi_power_supply_changed().
First, power_supply_changed() holds the battery wakelock and
releases the wakelock if battery supply change work is scheduled.
And then, qpnp-smbcharger-mmi driver set the supply changed flag
to be true, call smb_mmi_power_supply_changed() and wait for
battery supply change work completion, where it does not release
the wakelock as the supply changed flag becomes true.
Finally, the battery wakelock will not be released any more.

NXP patch to fix (CR)
Issue description:
No sound issue has been found in handheld mode
in one of Moto Projects, SurfNa project(tfa9871,
driver code Ver6.5.0). About 1/600 chance
root cause:
If set SBSL=1, the AMPE usually can be AMPE=1 automatically.
But sometimes can’t be set AMPE=1 by itself.
So AMPE must be set to 1 manually in code.
Dependency on automatic AMPE setting is not a wise way.
In driver 6.5.0, there’s no code to set AMPE during profile switch,
but boot up sequence has already been added.
Solution:
Add AMPE=1 operation in profile switching

When the System Suspends the running last reported SOC needs to
be reset. The reason is that the SOC could have moved a large
amount while sleeping. The curretn SOC needs to be recalculated
so that the changes is noticable to the User upon wakeup.
To do this keep track of the Suspend state as well as the fact
that the heartbeat has not run yet after a Suspend. The
WAS_SUSPEND bit will track this and then be cleared once the
heartbeat gets past the point that the information is not longer
needed. For Dual Batteries, this will force the last_reported_soc
to be updated with the current calculation rather then trying
to Monotonically adjust it slowly.

* waiting for valid power state to load DLKM
* new state "loading" that allows to hold on power state change

Note: It has been evaluated for test reporting DLKM only at this
