bq27000, bq27010 and upcoming bq34z100 have a single byte SoC
register. However except this similarity, bq34z100 is quite different
than bq27000/bq27010, so flag BQ27XXX_O_ZERO cannot be reused here. Add
a new bit flag describing that SoC is a single byte register.
No functional change for bq27000 and bq27010.

BQ27Z561 Battery monitor") and commit d74534c277 ("power:
bq27xxx_battery: Add support for additional bq27xxx family devices")
added support for new device types by copying most of the code and
adding necessary quirks.
However they did not copy the code in bq27xxx_battery_status()
responsible for returning POWER_SUPPLY_STATUS_NOT_CHARGING.
Unify the bq27xxx_battery_status() so for all types when charger is
supplied, it will return "not charging" status.

Some fault events like the over-current condition will get resolved
by the hardware, by e.g. disabling the port. As the status in the
interrupt status register is cleared on read when the fault is resolved,
the sysfs health property will only contain the correct health status
for the first time it is read after such an event, even if the actual
fault condition (like a VBUS short) still persists. To reflect this
properly in the property we cache the last health status and only update
the cache when a actual change happens, i.e. the ERR bit in the status
register flips, as this one properly reflects a continued fault condition.
The ALERT pin however, is not driven by the ERR status, but by the actual
fault status, so the pin will change back to it's default state when the
hardware has automatically resolved the fault by cutting the power. Thus
we never get an IRQ when the actual fault condition has been resolved and
the ERR status bit has been cleared in auto-recovery mode. To get this
information we need to poll the interrupt status register after some time
to see if the fault is gone and update our cache in that case.
To avoid any additional locking, we handle both paths (IRQ firing and
delayed polling) through the same single-threaded delayed work.

Prevents direct charging control in cable notification and only set the

that charging is enabled always in safe context.

cm_monitor(), where charging management starts, checks various charging
condition sequentially to decide next charging operation. However, as it
follows sequential process, cascaded if statements, it does some
jobs which have already done in the previous stage. This results in a
delay in decision making. Moreover, starting point of charging is spread
all around which makes maintain code and debugging difficult.
Both of the problems mentioned above become clean if it manages battery
charging focusing on battery status not following sequential condition
checking. Now, cm_monitor() moves battery state diagram and does the
optimal operation for current state. As a result, it reduces whole
monitoring time almost in half.

Both chips have charger and a fuel gauge.
This adds basic support for displaying the state of the battery and the
input power, settings are not modified. There are some defaults set via
OTP.
Charging also starts after plugging USB.
Known issues of the fuel gauge: There are drivers in the wild which disable
the fuel gauge at shutdown. If a kernel is booted without fuel gauge
support, after such a driver has been used, the fuel gauge will stay off
and decalibrate.
If this driver is used after that, it might display wrong values for charge
