When registering a power-supply device, either a of_node or the more
recent fwnode can be supplied. Since fwnode can also contain an of_node,
let's try to get rid of it.

The bit_types array just hold a list of valid enum power_supply_usb_type
values which map to 0 - 9. This can easily be represented as a bitmap.
This reduces the size of struct power_supply_desc and further reduces
the data section size by drivers no longer needing to store the array.
This also unifies how usb_types are handled with charge_behaviours,
which allows power_supply_show_usb_type() to be removed.

The "usb_type" property must be read-only for charger power-supply devices,
see: Documentation/ABI/testing/sysfs-class-power.
But the rt9467 driver allows writing 0/1 to it to disable/enable charging.
Other charger drivers use the "status" property for this and the rt9467
code also allows writing 0/1 to its "status" property and this does
the exact same thing as writing 0/1 to its "usb_type" property.
Drop write support for the "usb_type" property making it readonly to match
the ABI documentation. If userspace wants to disable/enable charging it
can use the "status" property for this.

It is spurious to bail-out on a wait_for_completion_timeout() call that
does NOT timeout.
Reverse the logic to return -ETIMEDOUT instead, in case of tiemout.

The current coding make 'charger-enable-gpio' control as real hardware
level. This conflicts with the default binding example. For driver
behavior, no need to use real hardware level, just logic level is
enough. This change can make this flexibility keep in dts gpio active
level about this pin.

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

RT9467 is a switch-mode single cell Li-Ion/Li-Polymer battery charger
for portable applications.
It integrates a synchronous PWM controller, power MOSFETs,
input current sensing and regulation, high-accuracy voltage regulation,
and charge termination. The charge current is regulated through
integrated sensing resistors.
The RT9467 also features USB On-The-Go (OTG) support. It also integrates
D+/D- pin for USB host/charging port detection.
