Extend properties supported by max17040 fuel gauge if it is accompanied
by different devices.
If max17040 is coupled with a charger, pass charger status since it should
match and max17040 has no dedicated status detection ability.
max17040_get_online can be reused for PRESENT property since if it is
online it must be present.
Finally, max17040 may be coupled with a dedicated thermal sensor which
monitors battery temperature so lets add support for iio channel to match
hw setup.
---
Changes from v1:
- documentation dropped monitored-battery and power-supplies (inherited
from inclusion)
- dropped passing charger health as battery health
- dropped patch for simple battery cell support
- switched iio_read_channel_raw to iio_read_channel_processed_scale
- switched iio_channel_get to devm_iio_channel_get
- re-organized implementation of temp channel (implemented in way
*_get_optional functions usually act)

Optionally pass status property from supplier if has support
for it. If cell is online assume it is present as well.

Since fuel gauge does not support thermal monitoring,
some vendors may couple this fuel gauge with thermal/adc
sensor to monitor battery cell exact temperature.
Add this feature by adding optional iio thermal channel.
